Description:
FIELD OF THE INVENTION 
     The present invention relates to an apparatus which can be connected to a network, and has a function of acquiring predetermined information in a designated device on the network, and browsing the information, and a print control method. 
     BACKGROUND OF THE INVENTION 
     In recent years, a multi-function printer to which many functions are added based on a digital copying machine is in practical use. More specifically, apparatuses such as a copy, facsimile, printer, scanner, and the like are integrated as one apparatus. In addition, a function of saving scanned image data in a hard disk or the like is added to that apparatus. 
     An operation panel used to operate these multiple functions becomes larger in size in recent years. Such operation panel can not only make operation settings of functions utilizing the scanner and printer, but also display for monitoring the operations and status of remote devices on the network and display Web contents (Web pages) using a browser function on its operation screen. 
     For example, Japanese Patent Application Laid-Open No. 11-237968 discloses a method which allows the network user to call a print selection mode to quickly identify Web pages so as to print them by a single and continuous batch processing, and can enqueue the identified Web pages, and a computer system that implements this method. Japanese Patent Application Laid-Open No. 11-237968 particularly relates to a print selection method which displays a plurality of choices and allows the user to select desired text for required print processing from them using a full-text target parameter or each individual parameter. In one example, the user can select any desired one from a list of available Hyperlinks on a target page for a subsequent print selection. The system prints according to print parameters selected by the user. For this purpose, the user quickly designates a list of selected pages and those at destinations of the Hyperlinks up to the designated level. The system saves the designation, and can start asynchronous print processing for all the selected pages at the same time. 
     However, according to the prior arts including Japanese Patent Application Laid-Open No. 11-237968, in order to print Web contents over a plurality of pages, the user must type in a desired URL, download Web contents information represented by HTML from a server at the destination of the URL, and display the Web contents on the screen. Then, the user determines whether or not they are to be printed and presses a print button, thus completing print processing. Therefore, the operation for displaying another page and pressing the print button must be repeated. 
     There are various display types of Web contents. For example, some Web contents are formed of a very long page in a format represented by HTML, or some other Web contents include a link such as “next page” to reduce the load of scrolling by the user, so that the next page is displayed by the user&#39;s clicking. In case of a long document, if the user wants to print upon browsing it, he or she need only press the “print” button once. By contrast, in a case where the Web contents consist of a plurality of pages, the user must alternately repeat page browsing and a print instruction, thus imposing a heavy operation load on the user. 
     SUMMARY OF THE INVENTION 
     Accordingly, the present invention is conceived as a response to the above-described disadvantages of the conventional art. 
     For example, an image forming apparatus and a print control method according to the present invention are capable of printing Web contents over a plurality of pages by a simple print instruction while minimizing user&#39;s operations.

     Preferred embodiments of the present invention will now be described in detail in accordance with the accompanying drawings. 
     The first to third embodiments as the best modes of carrying out the invention will be described hereinafter. These embodiments are merely specific examples for embodying the present invention, the present invention is not limited to these embodiments, and any other embodiments can be applies unless they have different principles. 
     Items common to respective embodiments will be explained first and those unique to each of the embodiments will then be explained with reference to the accompanying drawings. 
     Items Common to Respective Embodiments 
     (1) Network Arrangement 
       FIG. 1  is a diagram illustrating the arrangement of a network which accommodates a multi-function image forming apparatus common to each embodiment of the present invention. In this case, a copying machine having a data transmission/reception function is assumed as the multi-function image forming apparatus. 
     As shown in  FIG. 1 , a copying machine  1001  is connected to a LAN  1006  implemented by Ethernet® or the like together with a copying machine  1002  having functions equivalent to those of the copying machine  1001 , a facsimile apparatus  1003 , a database/mail server  1004 , and a client computer  1005 . Also, the copying machine  1001  is connected to a public communication line  1008  together with a facsimile apparatus  1007 . The copying machine  1001  has copy and facsimile functions, and also a data transmission function of scanning a document image, and transmitting scanned image data to respective apparatuses on the LAN  1006 . Also, since the copying machine  1001  has a PDL function, it can receive and print a PDL image designated by a computer connected on the LAN  1006 . 
     The copying machine  1001  can save an image scanned by itself, and a PDL image designated by a computer connected on the LAN  1006  in a designated box area in a hard disk  2004 , and can print an image saved in the box area. 
     The copying machine  1001  can receive data scanned by the copying machine  1002  via the LAN  1006 , and can save the received data in its hard disk  2004  and/or print it out. Also, the copying machine  1001  can receive an image from the database/mail server  1004  via the client computer  1005  and LAN  1006 , and can save the image in itself and/or can print it out. 
     The facsimile apparatus  1003  receives data scanned by the copying machine  1001  via the LAN  1006 , and can transmit that received data. The database/mail server  1004  is a server apparatus which receives data scanned by the copying machine  1001  via the LAN  1006 , stores it in a database, and transmits the data as an e-mail message. 
     The client computer  1005  is connected to the database/mail server  1004 , and can display desired data acquired from the database/mail server  1004 . Also, the client computer  1005  receives data scanned by the copying machine  1001  via the LAN  1006 , and can modify and edit the received data. The database/mail server  1004  may have a function as an HTTP (Hyper Text Transfer Protocol) server. In this case, Web contents stored in the database/mail server  1004  can be displayed using a Web browser of the client computer  1005  and a Web browser function of the copying machines  1001  and  1002  (to be described later). 
     The facsimile apparatus  1007  can receive data scanned by the copying machine  1001  via the public communication line  1008 , and can print out the received data. 
     (2) Principal Arrangement Block Diagram of Copying Machine  1001  as Image Forming Apparatus 
       FIG. 2  is a block diagram showing the principal arrangement of the copying machine  1001  as an image forming apparatus which is commonly applied to respective embodiments. 
     A controller unit  2000  connects a scanner  2070  as an image input device and a printer  2095  as an image output device, and performs control for implementing a copy function of printing out image data scanned by the scanner  2070  via the printer  2095 . Also, the controller unit  2000  connects the LAN  1006  and public communication line  1007  (WAN) and performs control for inputting/outputting image information and device information. 
     More specifically, the controller unit  2000  has a CPU  2001 , which loads and activates an operating system (OS) by a boot program stored in a ROM  2003 , and executes application programs stored in an HDD (hard disk drive)  2004  under the control of this OS, thus implementing various kinds of processing. A RAM  2002  is used as a work area of the CPU  2001 . 
     The RAM  2002  includes both volatile and non-volatile types. A volatile RAM provides an image memory area for temporarily storing image data as well as functioning as a work area, and is used to temporarily hold a browsed URL table and selected character strings (to be described later). On the other hand, a non-volatile RAM stores information of the image forming apparatus and the like, which is to be held even after power OFF. For example, the non-volatile RAM stores image-related parameters, and keywords which are selected frequently in a Web page (to be described later in this specification) in the form of lists. The HDD  2004  stores image data together with application programs. Information to be held even after power OFF may be stored in the HDD  2004 . 
     To the CPU  2001 , an operation unit I/F (operation unit interface)  2006 , network I/F (network interface)  2010 , modem  2050 , and image bus I/F (image bus interface)  2005  are connected via a system bus  2007  as well as the ROM  2003  and RAM  2002 . 
     The operation unit I/F  2006  is an interface with an operation unit  2012  having a touch panel, and outputs image data to be displayed on the operation unit  2012  to it. Also, the operation unit I/F  2006  outputs information input by the user at the operation unit  2012  to the CPU  2001 . 
     The network I/F  2010  is connected to the LAN  1006  and exchanges information with respective apparatuses connected to the LAN  1006  via the LAN  1006 . The modem  2050  is connected to the public communication line  1007 , and exchanges information via the public communication line  1007 . 
     The image bus I/F  2005  is a bus bridge which connects the system bus  2007  and an image bus  2008  that transfers image data at high speed, and converts data structures. On the image bus  2008 , a raster image processor (to be referred to as RIP hereinafter)  2060 , device I/F  2020 , scanner image processor  2080 , printer image processor  2090 , image rotation unit  2030 , thumbnail image generation unit  2035 , and image compression unit  2040  are connected. The RIP  2060  is a processor for developing PDL codes into bitmap image data. To the device I/F  2020 , the scanner  2070  and printer  2095  are connected. The device I/F  2020  converts synchronous image data into asynchronous image data and vice versa. 
     The scanner image processor  2080  performs correction, modification, and edition on input image data. The printer image processor  2090  applies printer correction, resolution conversion, and the like to print output image data. The image rotation unit  2030  rotates image data. The image compression unit  2040  compresses multi-valued image data to JPEG data, compresses binary image data to JBIG data, MMR data, MH data, or the like, and performs their decompression processes. 
     (3) Hardware Arrangement of Scanner  2070  and Printer  2095   
       FIG. 3  is a sectional view illustrating the hardware arrangement of the scanner (reader)  2070  and printer  2095  of the copying machine  1001  shown in  FIG. 1 . 
     The scanner  2070  and printer  2095  are integrally arranged, as shown in  FIG. 3 . The scanner  2070  mounts a document feeder unit  250 . The document feeder unit  250  feeds documents one by one onto a platen glass  211  in turn from the uppermost one, and discharges a document from the platen glass  211  to a discharge tray (not shown) every time the scan operation of the document is completed. 
     When a document is fed onto the platen glass  211 , the scanner  2070  turns on a lamp  212 , and starts movement of a moving unit  213  the document on the platen glass  211  is scanned by the movement of the moving unit  213 . During this scanning, light reflected by the document is guided to a CCD image sensor (to be referred to as CCD hereinafter)  218  via mirrors  214 ,  215 , and  216 , and a lens  217 , and an image on the document is formed on the imaging surface of the CCD  218 . The CCD  218  converts the image formed on the imaging surface into an electrical signal, which undergoes predetermined processing, and is then input to a controller unit  2000 . 
     The printer  2095  has a laser driver  321 , which drives a laser emission unit  322  on the basis of image data input from the controller unit  2000 . As a result, the laser emission unit  322  emits a laser beam according to the image data, and irradiates a photosensitive drum  323  while being scanned. An electrostatic latent image is formed on the photosensitive drum  323  by the irradiated laser beam, and is visualized as a toner image by toner supplied from a developer  324 . A print sheet fed from a cassette  311  or  312  is conveyed to a nip between the photosensitive drum  323  and a transfer unit  325  via a convey path in synchronism with the irradiation timing of the laser beam, and the toner image on the photosensitive drum  323  is transferred onto the fed print sheet by the transfer unit  325 . 
     The print sheet on which the toner image is transferred is fed to a fixing roller pair (heating roller and pressure roller)  326  via a conveyance belt, and the fixing roller pair  326  applies heat and pressure to the print sheet to fix the toner image on the print sheet on it. The print sheet that has left this fixing roller pair  326  is discharged into a discharge unit  330  by a discharge roller pair  327 . The discharge unit  330  comprises a sheet processing device which can apply post-processes such as sorting, stapling, and the like. When a two-sided print mode is set, the rotational direction of the discharge roller pair  327  is reversed after the print sheet is conveyed to the discharge roller pair  327 , and the print sheet is then guided to a re-feed conveyance path  329  by a flapper  328 . The print sheet guided to the re-feed conveyance path  329  is re-fed to the nip between the photosensitive drum  323  and transfer unit  325  again at the aforementioned timing, and a toner image is transferred onto the reverse face of this print sheet. 
     (4) Outer Appearance of Operation Unit  2012   
       FIG. 4  shows the arrangement of the operation unit  2012 . An LCD display unit  2013  has an LCD screen on which a touch panel sheet is adhered. The LCD display unit  2013  displays an operation window of the system, and when any of keys displayed on the LCD display unit  2013  is pressed, the LCD display unit  2013  sends its position information to the CPU  2001  of the controller unit  2000 . A start key  2014  is used, e.g., when the scan operation of a document image is to be started. 
     The start key  2014  has two-color, i.e., green and red LEDs  2018  at its central portion, and indicates based on the color of the ON LED if the start key  2014  is ready to use. A stop key  2015  is used to stop an active operation. 
     An ID key  2016  is used when the user inputs a user ID. The user inputs the ID and password when he or she logs into the copying machine  1001 . A reset key  2017  is used to reset settings from the operation unit. 
     (5) Operation Unit Window 
       FIG. 5  shows an example of an operation window to be displayed on the operation unit  2012 . 
     Touch keys which represent tabs for a plurality of functions such as copy ( 901 ), send/FAX ( 902 ), box ( 903 ), and browser ( 904 ) are displayed on the screen of the operation unit. A program required to display a Web browser is installed in the ROM  2003  of the controller unit  2000 , and the Web browser can be displayed in response to an instruction on the operation unit  2012 . The program required to display the Web browser may be stored in the HDD  2004 . 
     When the controller unit  2000  has five or more functions, a right-arrow key  905  is displayed on the right side of the four tabs of the copy, send/FAX, box, and browser functions. Upon depression of the right-arrow key  905 , for example, a tab of a function as a category other than the aforementioned ones (e.g., “printer” or the like) can be displayed. 
       FIG. 5  also shows an initial window of the copy function upon depression of the copy touch key  901 . A display area  906  pertains to the copy function: a field that displays “ready to copy” displays status displayed by the copy function on the upper portion of  FIG. 5 , and a field that displays the magnification, selected paper source, and the number of copies is located below. As touch keys used to set operation modes of the copy function, a no-magnification key, magnification key, paper selection key, sorter key, two-sided copy key, interrupt key, left- and right-arrow keys respectively used to reduce and increase a density of text and image for density adjustment, and auto key used to automatically adjust the density are displayed. Upon designation of operation modes which cannot be displayed on the initial window, an application mode key is pressed to hierarchically display setting windows in the area  906 . 
     A display area  907  displays status of the copying machine function ( 901 ). For example, this area displays, for example, an alarm message such as jam or the like, and a status message indicating that PDL print processing is in progress during PDL print processing. 
     When a system status/cancel touch key  908  is pressed, a window used to display device information of the copy function ( 901 ), and a window used to display print job status are displayed (not shown), and a job cancel instruction can be input from these windows. 
     Upon depression of the touch key of the send/FAX touch key  902 , a setting window (not shown) used to send an image scanned by the copy function ( 901 ) to an apparatus on the LAN  906  via e-mail or FTP, or to send such an image via FAX using the public communication line  1007  is displayed. 
     Upon depression of the box touch key  903 , a setting window (not shown) used to save an image scanned by the copy function ( 901 ) in the box area of the hard disk  2004 , to designate and print image data saved in the box area, or to send the designated image data to an apparatus on the LAN  1006  is displayed. 
     Upon depression of the browser touch key  904 , a browser window shown in  FIG. 6  is opened. A URL input field  911  is touched when a Web page is to be opened by designating its URL. When this field is touched, a soft keyboard (not shown) is displayed, and the user can designate the URL. 
     A display area  913  is that of a Web page. Reference numeral  927  denotes information of a Web page. A back key  914  is used to display the previous page. A forward key  915  is used to display the next page. An update key  916  is used to re-load and display the currently displayed page. A stop key  917  is used to cancel loading of the page. A home key  918  is used to move to a home page which is set in advance. 
     Reference numeral  924  denotes a scroll bar used to scroll the display area  913 . Reference numeral  923  denotes a button used to scroll the display area  913  upward; and  925 , a button used to scroll the display area  913  downward. Reference numerals  926 ,  928 , and  930  denote examples of information described in a given Web page. When such Web page is displayed, information described in this Web page consists of three pages, and the user can open his or her favorite one of the three pages by touching any desired one of displayed page number  930 . For example, in this case, a numeral “2” is displayed to be larger than other numerals among the displayed numbers  930 , and this indicates that the second page is open. This is merely an example, and the Web-page creator freely determines such window display rules. The information  928  is link text used to open the previous page of the current second page, i.e., the first page, and a link to the URL of the Web contents of the first page is set. The information  926  is link text used to open the third page, and a link to the URL of the Web contents of the third page is set. 
     A recording start button  921  is used to start recording of the URLs of the browsed Web pages. A recording stop button  922  is used to stop the recording of the URLs of the browsed Web pages. The URLs of the Web pages displayed on the operation window during an interval from a timing when the recording start button  921  is pressed to a timing when the recording stop button  922  is pressed are stored as a URL table on the non-volatile memory portion of the RAM  2002 . 
     The URL table will be described below with reference to  FIG. 7 . The URL table has a configuration shown in  FIG. 7 . “Page(n)” indicates the browsed page order, and “URL” indicates the browsed URL information. The URL table accumulates the URLs of the Web pages which are opened from a timing when the recording start button  921  is pressed to a timing when the recording stop button  922  is pressed. The URL table shown in  FIG. 7  indicates that three Web pages are browsed from a timing when the recording start button  921  is pressed to a timing when the recording stop button  922  is pressed, and this table stores the URLs corresponding to these pages. 
     In a case where a given Web page consists of, e.g., three pages, as shown in  FIG. 6 , and the user alternately displays the first to third pages by touching the information  930 , once all the URLs are recorded, even though the same page as that previously displayed is displayed, the same URL is not recorded. That is, three different URLs for the first to third pages are recorded in the URL table in this example. For example, consider a case where the user&#39;s instructions are “recording→start display 2nd page→display 1st page→display 2nd page→display 3rd page→recording stop”. In this case, upon depression of the recording start button, the values of the URL table are initialized. In other words, no data is stored in the table. Since the second page is displayed initially, the URL of the second Web page is registered in Page=1 of the URL table. Since the first page is browsed next, the URL of the first page of the Web page is registered in Page=2. When the second page is displayed again, it is checked in turn from Page=1 in this embodiment whether or not the same URL is stored. If the same URL is not stored, that URL is registered. Since the URL information of the second page has already been registered in Page=1, it is not registered. When the third page is displayed subsequently, since its URL is not registered in the URL table, Page=3 registers the URL of the third page. 
     Note that  FIG. 7  shows an example in which three Web pages are opened in the same Web site termed “AAAAA.co.jp”. However, opened pages may be from different Web sites. 
     Reference numeral  920  denotes a button used to open a window for print settings. Upon depression of this button, a window used for print settings (the number of copies, two-sided printing, sort, and the like) of the Web pages is displayed. By pressing a print start button  919 , print processing starts. The print start button  919  functions as a print mode designation key. Upon depression of this button, a print mode setting dialog shown in  FIG. 8  is displayed. 
     On the print mode setting dialog shown in  FIG. 8 , a “print from displayed page” button  931  used to print only the currently displayed page, a “print from URL table” button  932  used to sequentially load all the URLs stored in the URL table shown in  FIG. 7  and print the corresponding pages, and a cancel button  933  used to cancel print processing are displayed. When the user selects either the “print from displayed page” button  931  or “print from URL table” button  932 , a print preview window shown in  FIG. 9  opens. 
     Referring to  FIG. 9 , reference numeral  934  denotes a button used to close the print preview window;  935 , a button used to print the displayed print preview window;  936 , a button used to display the previous page of the print preview window; and  937 , a button used to display the next page of the print preview window. Upon depression of the print button  935  after confirmation of the preview, a print setting dialog (not shown) is displayed. The print setting dialog displays setting items about a method of printing a frame, and setting items about printing (the number of copies, two-sided printing, sort, and the like), and print processing starts upon depression of a print start instruction button (not shown). Note that the order of pages to be printed can be changed by operating a button (not shown) on the print preview window. Note that the order of pages to be printed may be changed on the print setting dialog in  FIG. 8 , or may be realized by additionally providing a window (not shown) that displays a list like the URL table shown in  FIG. 7 , and manually changing the order of the list. 
     (6) Description of PDL 
     PDL (Page Description Language: to be abbreviated as PDL hereinafter) data will be described below. PDL represented by PostScript® language of Adobe Systems Corporation is classified into the following three elements. 
     (a) Image description based on character codes 
     (b) Image description based on graphics code 
     (c) Image description based on raster image data 
     That is, PDL is a language that describes an image formed by combining the above elements, and data described in that language is called PDL data. 
       FIG. 10A  shows a description example of text information R 1301  shown in  FIG. 10B . L 1311  indicates a description that designates a character color, and numerals in parentheses represent the densities of Cyan, Magenta, Yellow, and Black in turn. The minimum density is 0.0, and the maximum density is 1.0. L 1311  designates a character color=black. In L 1312 , a character string “IC” is substituted in a variable String 1 . In L 1313  the first and second parameters indicate the x- and y-coordinates of the start coordinate position on a sheet where the character string is to be laid out, the third parameter indicates the character size, the fourth parameter indicates the character interval, and the fifth parameter indicates the character string to be laid out. As summarized, L 1313  instructs to lay out the character string “IC” from a coordinate position (0.0, 0.0) to have a size=0.3 and interval=0.1. 
     Likewise, in a description example of graphics information R 1302  shown in  FIG. 10B , L 1321  designates a line color as in L 1311 . In this case, L 1321  designates Cyan. L 1322  designates to draw a line. That is, the first and second parameters indicate the x- and y-coordinates of the start coordinate position of the line, and the third and fourth parameters indicate the x- and y-coordinates of the end coordinate position of the line. The fifth parameter indicates the thickness of the line. 
     Furthermore, in a description example of raster image information, in L 1331 , a raster image is substituted in a variable Image 1 . In this instruction, the first parameter indicates the image type and the number of color components of the raster image, the second parameter indicates the number of bits per color component, and the third and fourth parameters indicate the size of the raster image in both the x- and y-directions. The fifth and subsequent parameters indicate the raster image data. The number of raster image data is the product of the number of color components which form one pixel, the image size in the x-direction and the image size in the y-direction. In L 1331 , since the CMYK image is formed of four color components (Cyan, Magenta, Yellow, Black), the number of raster image data is (4×5×5)=100. Next, L 1332  indicates that Image 1  is to be laid out from a coordinate position (0.0, 0.5) to have a size of 0.5×0.5. 
       FIG. 10B  shows a state in which the above three image descriptions in one page are interpreted and rasterized to raster image data. R 1301 , R 1302 , and R 1303  are respectively obtained by developing the corresponding PDL data. These raster image data are developed on the RAM  2002  (or HDD  2004 ) for respective C, M, Y, and K color components in practice. For example, C=0, M=0, Y=0, and K=255 for R 1301  are written in the C, M, Y, and K areas of the RAM  2002 , and C=255, M=0, Y=0, and K=0 are written in the C, M, Y, and K areas for R 1302 . 
     PDL data to be handled by the copying machine  1001  is written on the RAM  2002  (or HDD  2004 ) as PDL data intact or the rasterized image data as described above, and is saved as needed. 
     (7) Document Integration of Web Page 
     A document integration method of browsed Web pages will be described below using  FIGS. 11A ,  11 B, and  12 . 
     In order to attain document integration, Web pages must be converted in advance into PDL data in a format that allows edit processing for respective pages. In order to generate data in the format for respective pages, a PDF format is well known, and it is ideal to convert Web pages using an Acrobat® Writer available from Adobe® Systems Corporation. 
       FIG. 11A  shows the first page of a Web page starting from Index, and Chapter 1  of  FIG. 11B  represents the second page of the Web page. A document of the “first page of the Web page” is a single and long page, but is divided into two pages if it is described in the PDL. The same applies to a document of the “second page of the Web page”.  FIGS. 11A and 11B  are expressed by PDL data, and are converted in advance into PDL data to allow edit processing for respective pages. 
     If data having a non-page format is input, such data is rasterized by the RIP  2060  of the copying machine  1001 , and is then processed by the image compression/data conversion unit for respective pages and is compressed as needed, so as to describe data in PDL data for respective pages. Then, the data can be dealt in unit of page. 
     Integration of PDL data will be described below using  FIGS. 11A ,  11 B, and  12 .  FIGS. 11A and 11B  show PDL data obtained by converting the first and second pages of the Web page into PDL format, respectively.  FIG. 12  shows PDL data obtained by reading and integrating both the original PDL files shown in  FIGS. 11A and 11B , and these original PDL files are converted into one PDL data. 
       FIG. 12  shows a merged file and PDL data. An “Index” part  701  corresponding to the first page of the Web page is converted into data including Page 1  and Page 2 , and a “Chapter 1 ” part  702  corresponding to the second page of the Web page is converted into data including Page 3  and Page 4 . 
       FIGS. 11A and 11B  will be described below using  FIG. 13 . Reference numeral  504  denotes data of the first page of the Web page. Reference numeral  505  denotes data of the second page of the Web page. Reference numeral  506  denotes information described in the Web pages. Reference numerals  507 ,  508 , and  509  denote page separators in the PDL. For example, the data  504  indicates that the Web page is separated into two pages at the position of the page separator  507 , and these two pages are output as print data  501  for the first page and  502  for the second page upon printing. Reference numeral  510  denotes a blank which may be formed on a paper sheet of the second page, and in which information  511  of the Web page is packed in the PDL level. That is, the first and second pages of the Web page are converted into PDL data, and are merged. Then, page separators are inserted at a position where no information is omitted in correspondence with the output paper size. In this manner, no blank is formed at the area  510 , thus saving paper sheets. 
     First Embodiment 
       FIG. 14  is a flowchart for explaining the print operation of a Web page according to the first embodiment of the present invention. 
     In step S 1401 , a Web page display window shown in  FIG. 6  is displayed upon depression of the browser button  904  shown in  FIG. 5 . It is checked in step S 1402  whether or not the recording start button  921  is pressed. If the recording start button  921  is pressed, the URL table is initialized in step S 1403  so that the URL table stores no data. 
     In step S 1404 , the URL table is searched from Page=1 to check whether or not a URL to be recorded has already been described in the URL table. If the URL to be recorded has already be registered, it is not registered in the URL table, and the flow jumps to step S 1406 . If the URL to be recorded is not registered, the URL of the currently displayed Web page is stored into the URL table in step S 1405 . 
     It is checked in step S 1406  whether or not the recording stop button  922  is pressed. If the recording stop button  922  is not pressed, it is further checked in step S 1407  whether or not the link button used to select another URL is touched. If no button is touched, the flow returns to step S 1406 . If the link button is touched in step S 1407  to select another page, a Web page is displayed in step S 1408 , and it is further checked in step S 1404  whether or not the URL of that Web page has already been registered in the URL table. For example, in case of Web pages which form one document by three pages, the processes in steps S 1404  to S 1408  are repeated once again, and if the control reaches step S 1405  again, then the three URLs are recorded in the URL table, as shown in  FIG. 7 . If the recording stop button  922  is pressed in step S 1406 , the URL recording is stopped, and the flow advances to step S 1409 . 
     It is checked in step S 1409  whether or not the print button  919  is pressed. If the print button  919  is pressed, a number reference value n in the URL table is reset to n=1 in step S 1410 . In step S 1411 , the n-th URL in the URL table is loaded. Since n=1 at this time, the first URL in the URL table is loaded. In this case, since http://AAAAA.co.jp/index2.html in  FIG. 7  corresponds to the first page, this URL is loaded. It is checked in step S 1412  whether or not a Web page can be displayed. If Web page data cannot be downloaded from the URL destination and causes an error display, a dialog indicating an error is displayed in step S 1420 . Furthermore, in step S 1415 , a reference counter of the URL table is increment by +1 (n=n+1). By contrast, if the Web page can be browsed in step S 1412 , that Web page is displayed in step S 1413 , and Web pages are integrated in step S 1414 . As the integration method, as described above, all Web pages in the URL table are converted into PDL data, which are integrated as if they were a single and long document. Then, page separators are inserted in correspondence with the output paper size when the integrated document is output. 
     If it is confirmed in step S 1416  that the Web pages are downloaded from all the URLs in the URL table, a preview of the print document is displayed in step S 1417 . The preview window is as shown in  FIG. 9 , and the user determines based on the preview if he or she wants to print it. If a print OK button is pressed in step S 1418  to determine to execute print processing, page separators are inserted. In step S 1419 , the already generated PDL data is rasterized by the RIP  2060  and raster image data is printed out. 
       FIGS. 15 and 16  show the print result of three Web pages using the present invention. As shown in  FIG. 15 , for example, there are Web pages for three pages loaded from the URL table. Note that respective Web pages have different lengths. As shown in  FIG. 16 , respective Web pages are converted into PDL data, data are packed in correspondence with the output paper size, and page separators are inserted. 
     Upon printing from the URL list shown in  FIG. 7 , if a 4in1, two-sided print mode is designated by designating a print layout, Web pages can be loaded from the URL list, and can be imposed in the designated layout upon printing. 
     The present invention also includes a method of displaying the URL list shown in  FIG. 7  on an operation window shown in  FIG. 17 . A URL list  950  shown in  FIG. 17  includes a recorded URL column  952  and Page number column  951 . In a Print column  953 , the user can select ● (print)/∘ (not print) using a toggle switch alternately indicating ON/OFF every time he or she touches.  FIG. 17  shows that Page  1  and Page  3  are to be printed, and Page  2  is not to be printed. 
     Also, upon displaying the URL list on an operation window, as shown in  FIG. 18 , a method of displaying thumbnails of Web pages, as indicated by  960 , may be used. In this case, upon displaying the URL list, Web pages to be displayed in the URL list are accessed, and their thumbnails are generated. In this manner, whether or not Web pages are to be printed can be easily determined based on the thumbnails in place of URL indications alone shown in  FIG. 17 . 
     Second Embodiment 
     The first embodiment has explained an example in which Web pages browsed from depression of the “recording start” button until depression of the “recording stop” button are recorded in the URL list. The second embodiment will explain an example in which Web pages to be recorded in the URL list are designated and recorded. 
       FIG. 19  shows an operation window according to the second embodiment, which is substantially the same as that shown in  FIG. 6 , except that a “print reserve” button  940  is added. 
     The print reserve button  940  is used to reserve a print operation of the currently browsed Web page. Upon depression of the print reserve button  940 , the URL of that Web page is recorded in the URL list. This recording processing will be described below using the flowchart shown in  FIG. 20 . 
       FIG. 20  is a flowchart for explaining the print operation of a Web page according to the second embodiment. 
     In step S 2001 , the URL table is initialized. This process is done when a reset button or the like is pressed. In step S 2002 , a Web page is displayed. Which button is pressed is checked in step S 2005 . If the pressed button is the print reserve button  940 , it is confirmed in step S 2003  in turn whether or not the current URL is stored in the URL table. If no current URL is stored in the URL table, the URL of the currently browsed Web page is saved in the URL table in step S 2004 . 
     After that, the current Web page is displayed again in step S 2002 . If it is confirmed in step S 2003  that the current URL is stored in the URL table, the Web page is displayed in step S 2002 . If the button used to display another Web page is pressed in step S 2005 , a new Web page is displayed in step S 2002 . If the print button  919  is pressed in step S 2005 , a number reference value (n) in the URL table is reset to n=1 in step S 2006 . In step S 2007 , the n-th URL in the URL table is loaded. Since n=1 at this time, the first URL in the URL table is loaded. In this case, since http://AAAAA.co.jp/index2.html in  FIG. 7  corresponds to the first page, this URL is loaded. It is checked in step S 2008  whether or not a Web page can be displayed. If Web page data cannot be downloaded from the URL destination and causes an error display, a dialog indicating an error is displayed in step S 2012 . Furthermore, in step S 2011 , a reference counter of the URL table is incremented by +1 (n=n+1). By contrast, if it is confirmed in step S 2008  that the Web page can be browsed, that Web page is displayed in step S 2009 , and Web pages are integrated in step S 2010 . 
     As the integration method, as described above, all Web pages. in the URL table are converted into PDL data, which are integrated as if they were a single and long document. Then, page separators are inserted in correspondence with the output paper size when the integrated document is output. 
     If it is confirmed in step S 2013  that the Web pages are downloaded from all the URLs in the URL table, a preview of the print document is displayed in step S 2014 . The preview window is as shown in  FIG. 9 , and the user determines based on the preview if he or she wants to print it. If print processing is determined to be executed in step S 2015 , page separators are inserted. In step S 2016 , the already generated PDL data is rasterized by the RIP  2060  and raster image data is printed out. 
     In this way, since the URLs of only print-reserved Web pages of those which are browsed are recorded in the URL list, the print-reserved Web pages can be output by a single print command upon depression of the print button. 
     In the second embodiment as well, a print layout may be designated, and Web pages may be loaded from the URL list and may be imposed in the designated layout upon printing, as has been described in the first embodiment. 
     In the second embodiment as well, the user may select ● (print)/∘ (not print) using a toggle switch alternately indicating ON/OFF every time he or she touches the URL list, as described in the first embodiment. In this case, Web pages may be displayed as thumbnail images to facilitate user&#39;s print decision. 
     Third Embodiment 
     As the recording means of the browsed URLs in the URL table shown in  FIG. 7 , in addition to recording of URLs by providing the recording start and recording end buttons of URLs as described in the first embodiment, in this embodiment, a case where Hypertext data in a Web page is searched using a keyword, and if the keyword hits given Hypertext, a link destination described in the Hypertext data is displayed, and the URL at that time is stored into the table will be explained. 
       FIG. 21  is a flowchart showing processing for registering a touched Hypertext character string. In step S 1501 , the user inputs a user ID and password to log into the system. In step S 1502 , a character string table of the login user is loaded. In step S 1503 , a URL is input. In step S 1504 , a Web page is displayed. It is checked in step S 1505  whether or not a Hypertext character string is touched. If the Hypertext character string is touched, the Hypertext character string designated by touching is stored in the character string table in step S 1506 . The registered Hypertext character string is stored in a character string table shown in  FIG. 22 . 
     The character string table will be described below. Referring to  FIG. 22 , “UserID” indicates the login user name. A table is assured for each user. Touched keywords are stored in a keyword column, and an order column indicates a list of touched keywords which are sorted in descending order of frequency of their occurrence. 
     Processing for searching the character string table for character strings in the order of touched frequency, transferring URLs to the URL table, and printing corresponding Web pages will be described below using  FIG. 23 . That is, in the third embodiment, when the user accesses a given Web site and prints its page, it is confirmed whether or not a Web page to be printed includes character strings registered in the character string table. If the registered character strings are found, pages related to them are also acquired and printed. In this manner, a load on the user&#39;s operation is reduced. For example, as shown in  FIG. 22 , if an HTML character string “next” with a higher frequency of touching is found, pages related to that character string are printed all at once. 
     In step S 1601 , the user inputs a user name and password to login the system. In step S 1602 , a character string table of that login user is loaded. It is confirmed in step S 1603  whether or not a URL is input. If the URL is input, a Web page is displayed in step S 1604 . 
     It is checked in step S 1605  whether or not the print button  919  is pressed. If the print button is pressed, the flow advances to step S 1606 . It is checked in step S 1606  whether or not an auto print button is pressed. If the auto print button is not pressed, the flow jumps to step S 1620  to print the currently browsed Web page, thus ending the processing. 
     By contrast, if the auto print button is pressed in step S 1606 , the flow advances to step S 1607  to set the number of table data of the character string table in a variable S. Since there are five table data in case of  FIG. 22 , S=5. In step S 1608 , the value of a reference pointer is reset to m=1. In step S 1609 , the reference pointer m indicating the reference position of the character string table is compared with the number (S) of table data in the character string table. In the example shown in  FIG. 22 , since five touched character strings are listed, S=5. It is checked in step S 1609  whether or not m≦S. This step checks if the character string to be referred to in the table reaches the last reference position. If m≦S, the m-th character string in the character string table is referred to in step S 1610 . In case of m=1, the Web page is searched for a Hypertext character string “next”. If no character string is found, m=m+1 in step S 1621 . That is, m=2, and the Web page is similarly searched for a Hypertext character string “next page”. 
     The search method will be described below using  FIG. 24 . In  FIG. 24 , reference numeral  1804  denotes a Web page. Reference numeral  1803  denotes information described in the Web page. The Web page includes text, photo data, graphics data, and the like. Reference numeral  1801  denotes a Hypertext character string which instructs to move to the previous page of the current Web page; and  1802 , a Hypertext character string which similarly instructs to move to the next page of the current Web page. By touching the Hypertext part, a linked Web page is opened. For example, “previous page”  1801  displays previous.html, as indicated by  18 - a,  and “next page”  1802  displays next.html, as indicated by  18 - b , when they are touched. 
     In step S 1611 , the link destination URL of the found character string is recorded in the p-th position of the URL table. In step S 1612 , a Web page corresponding to that URL is displayed. In step S 1613 , p=p+1, and a link destination URL of the character string with the next higher frequency of touching occurrence is acquired. 
     Upon completion of the search processing of all the character strings and acquisition of the link destination Web page URLs in step S 1609 , the flow advances to step S 1614 . 
     In steps S 1614  to S 1617 , Web page data registered in the URL table are acquired. 
     The acquired Web pages are integrated by the method described in the first embodiment in step S 1618 , and a preview of the print document generated by integrating the Web pages is displayed in step S 1619 . 
     In step S 1620 , print processing is finally executed. 
     In the third embodiment as well, a print layout may be designated, and Web pages may be loaded from the URL list and may be imposed in the designated layout upon printing, as has been described in the first embodiment. 
     In the third embodiment as well, the user may select ● (print)/∘ (not print) using a toggle switch alternately indicating ON/OFF every time he or she touches the URL list, as described in the first embodiment. In this case, Web pages may be displayed as thumbnail images to facilitate user&#39;s print decision. 
     Effect of Embodiments 
     According to each of the above embodiments, the user can print an HTML document including a plurality of pages by issuing only one print instruction without turning pages. In other words, there is no need for performing a series of operations for browsing the HTML document and issuing a print instruction for each page. The browsed HTML document can be converted into PDL data, and page separators can be inserted in correspondence with the output paper size. Hence, information of Web pages can be packed, resulting in paper savings. 
     According to each of the above embodiments, Web pages can be printed at the same time using the URL list in place of repetition of Web page browsing and Print button depression unlike in the conventional Web page print processing. This allows the user to freely determine a layout on one print page. That is, this means that, for example, four pages can be laid out on two faces of one sheet of print paper like in the 4in1, two-sided print mode. In this way, output paper sheets can be saved. 
     In the aforementioned embodiments, a multi-function image forming apparatus such as a copying machine having a data transmission/reception function has been exemplified. The Web page print processing implemented by this apparatus can also be implemented by a print system including a personal computer and printer. For example, in an environment in which a Web browser and printer driver are installed in that personal computer, the printer driver may have a document integration function of Web pages. In this manner, the same functions as those described in the above embodiments can be implemented, and the same effects can be achieved. 
     In the aforementioned embodiments, the document integration processing is executed after HTML data of the browsed pages are converted into PDL data. However, the present invention is not limited to such specific processing. For example, the document integration processing may be done using HTML data, and the integrated HTML data may then be converted into PDL data. 
     As many apparently widely different embodiments of the present invention can be made without departing from the spirit and scope thereof, it is to be understood that the invention is not limited to the specific embodiments thereof except as defined in the claims. 
     CLAIM OF PRIORITY 
     This application claims priority from Japanese Patent Application No. 2004-268709 filed on Sep. 15, 2004, which is hereby incorporated by reference herein.
