DETAILED DESCRIPTION OF THE EMBODIMENTS
Reference will now be made in detail to the present embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to the like elements throughout. The embodiments are described below in order to explain the present invention by referring to the figures.
FIG. 1 is a block diagram explaining an apparatus to generate XHTML-Print printing data according to an embodiment of the present invention. The apparatus includes an XHTML-Print printing data setting unit 110, an XHTML-Print extension data generation unit 130, an XHTML-Print basic data storage unit 140, and an XHTML-Print printing data generation unit 150.
In the present embodiments, XHTML-Print basic data, XHTML-Print extension data, and XHTML-Print printing data are all XHTML-Print data. It is understood that data described in a markup language other than the XHTML language can also be applied, instead of the XHTML-Print data, in the embodiments.
The XHTML-Print printing data setting unit 110, the XHTML-Print extension data generation unit 130, the XHTML-Print basic data storage unit 140, and the XHTML-Print printing data generation unit 150 are all included in a terminal, and an image forming apparatus is connected to the terminal by a wired or wireless connection. However, it is understood that, according to other aspects, the terminal may be connected to a data storage apparatus, such as a network sever, and/or may store the XHTML-Print data in a storage unit or a recordable medium, such as a CD, disk, DVD, flash memory, or SD card. The image forming apparatus can print printing data described in an XHTML-Print language, i.e., XHTML-Print printing data (XHTML-Print Contents). Examples of the terminal include a mobile phone, a digital camera, a computer, and a personal digital assistant (PDA). Also, examples of the image forming apparatus include a printer and a multi-function peripheral (MFP) having a printer function.
Data desired to be printed among data stored in the terminal may be data having standardized contents (standard data). The standard data is data whose contents are classified by standardized elements. Accordingly, standard data items of an identical type have common elements. That is, a standard data item, such as a specific text message, has the same elements as a same-type standard data item, such as another test message. Short message service (SMS) data, multimedia messaging service (MMS) data, and e-mail data are examples of the standard data types. For example, in the case of SMS data, standard data elements can include data corresponding to a caller (From), data corresponding to a callee (To), data corresponding to message contents (Message), data corresponding to a received time (Time), data corresponding to a degree of importance (Priority Level), data corresponding to a security requirement degree (Privacy Level), and/or data corresponding to accumulated response times (Number of Replies). According to an aspect of the present invention, From, To, Message, Time, Priority Level, Privacy Level, and Number of Replies are standardized elements of the SMS data.
The XHTML-Print printing data setting unit 110 sets printing-related options to determine contents to be printed from among contents of one or more standard data items desired to be printed. Examples of the printing-related options may be a size of a print medium the XHTML-Print printing data will be printed on, which standard data items will be printed, and data items of which element will be printed from among standard data items desired to be printed.
The XHTML-Print printing data setting unit 110 includes a print medium size information storage unit 112, a print medium size specifying unit 114, a user interface unit 116, a standard data storage unit 118, a standard data selection unit 120, an element extraction unit 122, and/or an element selection unit 124. However, it is understood that according to other aspects, the XHTML-Print printing data setting unit may include other units to store and/or select other types of printing-related options.
The print medium size information storage unit 112 stores print medium size information. Here, the paper size information is information about available sizes of print media on which XHTML-Print printing data is to be printed. The print media may be paper, or any type of tangible medium on which content may be printed, such as a transparency.
The print medium size specifying unit 114 commands the user interface unit 116 to display the print medium size information stored in the print medium size information storage unit 112. In this case, the user interface unit 116 displays the stored print medium size information. By doing so, the user can recognize what sizes of print media on which XHTML-Print printing data may be printed are available.
Then, the user may specify a desired size through the user interface unit 116 or by manipulating keys disposed on the terminal. According to other aspects, the user may specify a desired size through other methods and/or devices, such as a touch screen and/or a scroll wheel. By doing so, the paper size specifying unit 114 specifies the size selected by the user from among the stored paper sizes. Also, the print medium size specifying unit 114 reads information on the specified size from the stored print medium size information, and outputs the read information on the specified size to the XHTML-Print extension data generation unit 130.
The standard data storage unit 118 stores one or more standard data items. The user interface unit 116 displays the stored standard data according to an instruction from the standard data selection unit 120. By doing so, the user can recognize which standard data items are stored in the terminal. Then, the user can select one or more standard data items desired to be printed through the user interface unit 116 or by manipulating keys disposed on the terminal, and/or by other methods, such as a touch screen and/or a scroll wheel. By doing so, the standard data selection unit 120 can select one or more standard data items desired to be printed from among the stored standard data items. Meanwhile, the standard data selection unit 120 outputs the selected standard data to the XHTML-Print extension data generation unit 130.
The element extraction unit 122 analyzes elements of each of the selected standard data items. By doing so, the element extraction unit 122 extracts one or more elements appearing in the selected standard data, and commands the user interface 116 to display the extracted elements. The user interface unit 116 then displays the extracted elements. Also, the element extraction unit 122 classifies the selected standard data items in relation to extracted elements, and matches the classified data items with the extracted elements.
The element selection unit 124 selects one or more elements desired to be printed by the user from among the displayed elements. For this, the element selection unit 124 displays, for example, a window to request selection of elements desired to be printed through the user interface unit 116. Then, the user may select elements desired to be printed through the user interface 116 or by manipulating keys, and/or other methods, such as a touch screen and/or a scroll wheel, disposed on the terminal. By doing so, the element selection unit 124 selects elements desired to be printed.
If elements are thus selected, the element selection unit 124 provides information on the classified data matched with the selected elements and the selected elements to the XHTML-Print extension data generation unit 130.
The XHTML-Print extension data generation unit 130 generates XHTML-Print extension data, by using the print medium size specified by the print medium size specifying unit 114, the one or more standard data items selected by the standard data selection unit 120, the one or more elements extracted by the element extraction unit 122 and the classified data items corresponding to the elements, and the one or more elements selected by the element selection unit 124.
The XHTML-Print basic data storage unit 140 stores essential XHTML-Print basic data that is included in XHTML-Print printing data. The XHTML-Print extension data generated in the XHTML-Print extension data generation unit 130 can be inserted into XHTML-Print basic data.
The XHTML-Print printing data generation unit 150 reads the XHTML-Print basic data stored in the XHTML-Print basic data storage unit 140, and generates XHTML-Print printing data by inserting the generated XHTML-Print extension data into the read XHTML-Print basic data.
FIGS. 2A through 2I are reference diagrams explaining a principle of generating XHTML-Print printing data when standard data is SMS data, according to an embodiment of the present invention.
The user interface unit 116 displays a window as illustrated in FIG. 2A according to an instruction of the print medium size specifying unit 114. Referring to FIG. 2A, the XHTML-Print printing data may be printed on a print medium with a size of 4×6 inch (portrait), 6×4 inch (landscape), A4 portrait, A4 landscape, letter portrait, or letter landscape. It is understood that other print media sizes, such as legal portrait and/or legal landscape, may be provided.
If the print medium size specifying unit 114 specifies printing of XHTML-Print printing data on a print medium with a size of 6×4 (landscape) without a margin, the XHTML-Print extension data generation unit 130 generates XHTML-Print extension data as @page {size: 6 in 4 in; margin: 0 in;}.
Likewise, if the print medium size specifying unit 114 specifies printing of XHTML-Print printing data on a print medium with a size of A4 portrait without a margin, the XHTML-Print extension data generation unit 130 generates XHTML-Print extension data as @page {size: A4 portrait; margin: 0 in;}.
Similarly, if the print medium size specifying unit 114 specifies printing of XHTML-Print printing data on a print medium with a size of A4 landscape without a margin, the XHTML-Print extension data generation unit 130 generates XHTML-Print extension data as @page {size: A4 landscape; margin: 0 in;}.
Also, if the print medium size specifying unit 114 specifies printing of XHTML-Print printing data on a print medium with a size of letter portrait without a margin, the XHTML-Print extension data generation unit 130 generates XHTML-Print extension data as @page {size: letter portrait; margin: 0 in;}.
Similarly, if the print medium size specifying unit 114 specifies printing of XHTML-Print printing data on a print medium with a size of letter landscape without a margin, the XHTML-Print extension data generation unit 130 generates XHTML-Print extension data as @page {size: letter landscape; margin: 0 in;}.
However, as illustrated in FIG. 2A, since the print medium size specifying unit 114 specifies printing of XHTML-Print printing data on a print medium with a size of 4×6 inch (portrait), the XHTML-Print extension data generation unit 130 generates XHTML-Print extension data as @page {size: 4 in 6 in; margin: 0 in;}.
The user interface unit 116 can display all SMS data stored in the standard data storage unit 118 according to an instruction from the standard data selection unit 120. Referring to FIG. 2B, the user interface unit 116 displays a total of 6 SMS data items.
The standard data selection unit 118 can select one or more SMS data items desired to be printed from among the displayed SMS data items. Referring to FIG. 2B, the standard data selection unit 118 selects two SMS data items (a first SMS data item and a third SMS data item) from among the displayed SMS data items.
The element extraction unit 122 analyzes each of the selected SMS data items, and extracts one or more elements appearing in the selected SMS data items. In this case, the user interface unit 116 displays the extracted elements. Referring to FIG. 2C, the elements appearing in the first SMS data item are a caller (From), a callee (To), message contents (Message), a received time (Time), a degree of importance (Priority Level), a security requirement degree (Privacy Level), and accumulated response times (Number of Replies). Also, the elements appearing in the third SMS data item are caller (From), a callee (To), message contents (Message), and accumulated response times (Number of Replies).
Meanwhile, it may be impossible to select elements that cannot be generated as XHTML-Print printing data by the terminal from among the extracted elements. Also, the elements that cannot be selected may be distinguished from the other elements, as in FIG. 2C where the elements that cannot be selected are shaded. For example, if a number for replies (Number for reply) is an element that cannot be generated as XHTML-Print printing data by the terminal, it may be distinguished from other elements. According to other aspects, the elements that cannot be generated as XHTML-Print printing data may be distinguished by other methods, such as a different font, color, or style, or may not be displayed at all.
The element selection unit 124 selects one or more elements desired to be printed by the user from among the displayed elements. Referring to FIG. 2D, the one or more elements desired to be printed by the user are a caller, a callee, message contents and a received time.
Meanwhile, the extracted elements may be divided into header elements and message elements. Here, the message elements are elements indicating the contents of a message and the header elements are elements excluding the message elements. That is, a caller, a callee, and a received time are examples of header elements and message contents is a message element. In the following examples, the style that each of these elements is displayed is set as a default. However, the user may set the style for each element as desired by the user. To do this, in the XHTML-Print printing data setting unit 110 according to the present embodiment, a style database (not shown), a style reading unit (not shown) and a style setting unit (not shown) may be provided. In this case, the style reading unit (not shown) receives an input about a style desired by the user, reads a style corresponding to the input from the style database (not shown), and provides the style to the style setting unit (not shown). Then the style setting unit (not shown) sets the style of the elements according to the received style.
FIG. 2E illustrates XHTML-Print basic data stored in the XHTML-Print basic data storage unit 140, and FIG. 2F illustrates XHTML-Print printing data that is XHTML-Print basic data into which XHTML-Print extension data is inserted. XHTML-Print extension data generated by using the contents specified in the print medium size specifying unit 114, for example, @page {size: 4 in 6 in; margin: 0 in;}, is inserted into the XHTML-Print basic data as indicated by subscript 1 shown in FIG. 2F.
The XHTML-Print extension data generation unit 130 generates XHTML-Print extension data by using the elements selected by, for example, the element selection unit 124 and the classified data items corresponding to the elements. For this, the XHTML-Print extension data generation unit 130 generates XHTML-Print extension data for each of the elements selected by the element selection unit 124, excluding message contents, as follows:















<tr>









<td class= “td1”>









selected elements









</td>



<td class= “td2”>



:



</td>



<td>









data corresponding to the selected elements









</td>









</tr>










This generated XHTML-Print extension data is inserted into the XHTML-Print basic data, as indicated by subscripts 2, 3, and 4 shown in FIG. 2F.
Also, in the case of the message contents among the elements selected by the element selection unit 124, the XHTML-Print extension data generation unit 130 generates XHTML-Print extension data by using </br> indicating the end of a row for each row of the message. This generated XHTML-Print extension data is inserted between <div class=“BodyBox”> and </div> of the XHTML-Print basic data, as indicated by subscript 5 shown in FIG. 2F.
FIG. 2G illustrates an example of a printed result on which XHTML-Print printing data generated by the XHTML-Print printing data generation unit 150 is printed. As illustrated in FIG. 2G, the size of SMS data can be variably determined with respect to the quantity of the SMS data. That is, FIG. 2F illustrates XHTML-Print data in which a size for printing SMS data is determined with respect to the quantity of the SMS data.
FIG. 2H illustrates another example of a printed result on which XHTML-Print printing data generated by the XHTML-Print printing data generation unit 150 is printed. As illustrated in FIG. 2H, the size for printing the SMS data may also be determined irrespective of the quantity of the SMS data. Thus, in order to determine the size for printing the SMS data irrespective of the quantity of the SMS data, the XHTML-Print printing data may be described as illustrated in FIG. 2I.
FIGS. 3A through 3D are reference diagrams explaining a principle of generating XHTML-Print printing data when standard data is MMS data, according to an embodiment of the present invention. More specifically, FIGS. 3A and 3C illustrate printed results desired by the user.
