The following describes an embodiment of the present invention with reference to Figures.
FIG. 1 is a block diagram showing a configuration of a printing system 1 in accordance with an embodiment of the present invention. As shown in FIG. 1, the printing system 1 is provided with a personal computer (hereinafter simply referred to as a PC) 10, a network 11, and the first to third printers 21 to 23. In the printing system 1, the PC 10 is connected to the first to third printers 21 to 23 via the network 11. The first to third printers 21 to 23 each may be, for example, a MFP (multi function printer).
The PC 10 has a printer driver installed thereon. Therefore, the PC 10 of the present embodiment serves as a printer control device. The printer driver is a so-called shared printer driver (universal printer driver) compatible with a plurality of printers by a single printer driver. The PC 10 displays a user interface on a display section 104. This is a function of the printer driver.
FIG. 2 is a block diagram showing a configuration of the PC 10. The PC 10 includes a control section 101, an operation section 102, a storage section (storage device) 103 and the display section (display means) 104.
The control section 101 controls functions of all user interfaces and an operation of the PC 10 which operation relates to printing. Specifically, the control section 101 creates a user interface for selecting a printer to be employed, a user interface for setting a print setup corresponding to a selected printer and like user interfaces, and causes the display section 104 to display these user interfaces. The control section 101 also creates print preview data for displaying a print preview that schematically shows data to be printed by the printer which data is determined by a user (hereinafter referred to as user determination data), and causes the display section 104 to display the print preview of the data. Further, the control section 101 creates print data for printing the user determination data by use of any one of the printers.
The operation section 102 includes input devices such as a mouse and a keyboard, and transmits an operation of a user to the storage section 103. The storage section 103 may be the storage devices such as a hard disk and a memory, and stores preview data, various setup information and the like. The display section 104 is controlled by the control section 101 thereby displaying various information.
FIG. 3 is a block diagram showing a configuration of the control section 101 of the PC 10 shown in FIG. 2. As shown in FIG. 3, the control section 101 includes a print preview creation section (print preview creation means) 222, a display control section (display control means) 223, a print instruction section (print instruction means) 224, a printer searching section (printer searching means) 225, a print setup change section (print setup change means) 226, and a print setup storage processing section (print setup storage processing means) 227.
The printer searching section 225 searches for the printers (the first to third printers 21 to 23) connected to the network 11, and acquires print setup information on a print setup set in the respective printers (the first to third printers 21 to 23) extracted by the searching operation. The printer searching section 225 also acquires printer information on a function of the respective printers from the respective printers (the first to third printers 21 to 23) extracted by the searching operation. The printer searching section 225 then causes to store, in the storage section 103, the acquired print setup information and printer information in such a manner that the acquired print setup information and printer information are correlated with the respective printers corresponding to these information.
The storage section 103 stores various information on the first to third printers 21 to 23 extracted by the searching operation of the printer searching section 225.
The print preview creation section 222 creates print preview data 228 of user determination data for the respective first to third printers 21 to 23 extracted by the searching operation of the printer searching section 225. The print preview data 228 is data for displaying a print preview that schematically shows an image to be printed by a printer. An application 221 for creating the print preview data 228 is preinstalled on the PC 10.
The display control section 223 causes an identical display section 104 to simultaneously display the pieces of print preview data created by the print preview creation section 222. The display section 104 displays the pieces of print preview data in such a manner that the pieces of print preview data are associated with the respective printers corresponding to the pieces of print preview data and arranged on the identical display section 104. In this case, the display control section 223 reads the print setup information of the printers (the first to third printers 21 to 23) from the storage section 103, and causes the display section 104 to display the print preview data corresponding to the respective printers in such a way that the read print setup information is reflected on the print preview data.
The print setup change section 226 receives an instruction, from a user, for changing a print setup. In a case where the print setup change section 226 receives, from a user, the instruction for changing the print setup corresponding to a printer determined by the user, the print setup change section 226 extracts print setup information corresponding to the printer from the storage section 103, and changes the extracted print setup according to the instruction for changing.
In a case where an instruction for storing the changed print setup information is inputted from a user, the print setup storage processing section 227 stores, in the storage section 103, the print setup information changed by the print setup change section 226.
The print instruction section 224 converts the user determination data into print data for printing the user determination data by use of a determined printer, and outputs the converted print data to the determined printer.
FIG. 4 is a view showing a state where the display section 104 controlled by the display control section 223 displays a print preview, that is, a view showing a print preview display screen.
As shown in FIG. 4, the print preview display screen simultaneously displays a print preview 201 corresponding to the first printer 21, a print preview 202 corresponding to the second printer 22 and a print preview 203 corresponding to the third printer 23. In a case where the user determination data contains data equivalent to a plurality of pages, the respective print previews 201 to 203 displayed on the first page of the plurality of pages are displayed. Further, check boxes (employed printer determination sections) 306 to 308 for selecting a printer to be employed (default printer) by use of, for example, a pointing device are provided in a region next to a region where the print previews 201 to 203 are displayed. As shown in FIG. 4, the check box 306 is checked. This means that the first printer 21 is set as a default printer.
A check box 301, an input section (named print setup information extraction instruction section) 302 and an input section (sort instruction section) 303 are provided, in this order from above, above the region where the print previews 201 to 203 are displayed. The check box 301 is a check box for selecting reflecting, on all previews, a print setup of the default printer. The input section 302 is an input section for extracting a stored print setup on which a given name is put.
The input section 303 is an input section for determining a condition under which the first to third printers 21 to 23 are sorted. As shown in FIG. 4, resolution is selected in the input section 303. In this case, the print previews 201 to 203 corresponding to the first to third printers 21 to 23 are displayed from above on the print preview display screen in an increasing or decreasing order of the resolution of the print previews 201 to 203.
The above-described sorting can be conducted after the following process. The printer searching section 225 acquires the print setup information on the print setup set in the respective printers (the first to third printers 21 to 23) and the printer information on the function of the respective printers (the first to third printers 21 to 23) in a case where the printer searching section 225 searches for the printers (the first to third printers 21 to 23) connected to the network 11. Thereafter, the printer searching section 225 correlates the acquired printer information with a printer having the printer information, and causes the storage section 103 to store the printer information in correlation with the printer.
Further, an input section 304 and an input section 305 are provided, in this order from above, below the region where the print previews 201 to 203 are displayed. The input section 304 is an input section for instructing to display a detailed print preview (hereinafter referred to as a detail preview) corresponding to a printer whose check box 306, 307 or 308 is checked. As shown in FIG. 4, the check box 306 of the first printer 21 is checked. Therefore, in a case where the input section 304 is operated, a detail preview (detailed print preview) corresponding to the first printer 21 is displayed.
The input section 305 is an input section for instructing the printer whose check box 306, 307 or 308 is checked to print. As shown in FIG. 4, the check box 306 of the first printer 21 is checked. Therefore, in a case where the input section 305 is operated, the first printer 21 prints data whose print preview is displayed.
FIG. 5 is a view showing a state where a detail preview is displayed on the display section 104 controlled by the display control section 223, that is, a view showing a detail preview display screen displayed in a case where the input section 304 for instructing to display the detail preview is operated on the print preview display screen shown in FIG. 4.
As shown in FIG. 5, the detail preview display screen displays a detail preview 324 of the print preview 201 corresponding to the checked check box 306. In a case where the user determination data corresponding to the print preview 201 includes data equivalent to a plurality of pages, it is possible to display the detail preview 324 of the data equivalent to the plurality of pages. Specifically, it is possible to sequentially turn a displayed page by operating any one of two arrows 325 that is provided below the detail preview 324.
Further, a print setup section 323 is provided in a region next to a region where the detail preview 324 is displayed. The print setup section 323 is an input section for setting 2-UP printing, double-sided printing, monochrome printing, color printing or other printing. 2-UP printing is printing by which data equivalent to 2 pages is printed on one page. Further, a check box (first print setup storage instruction section) 321 and an input section (second print setup storage instruction section) 322 are provided, in this order from above, above the detail preview 324. The check box 321 is a check box for instructing to store a print setup set by the print setup section 323, that is, a print setup changed by the print setup change section 226. The input section 322 is an input section not for reflecting, on the print setup information stored in the storage section 103, the print setup set by the print setup section 323, that is, the print setup changed by the print setup change section 226 (updating the print setup information) but for instructing to store the print setup on which a name different from the name put on the print setup information is put.
The print setup section 323 is controlled by the display control section 223 and the print setup change section 226. The check box 321 is controlled by the print setup change section 226. Specifically, the print setup set by the print setup section 323 is reflected on the detail preview 324 by the display control section 223. In a case where the check box 321 is checked, the print setup change section 226 updates, according to the print setup set by the print setup section 323, the print setup information on a printer corresponding to the detail preview 324 which print setup information is stored in the storage section 103.
The following describes an operation of the PC 10 serving as the print control device that has the above-described arrangement, with reference to the flowchart shown in FIG. 6.
In a case where certain application software installed on the PC 10 instructs to print user determination data (S401), the printer searching section 225 searches for the printers (the first to third printers 21 to 23) connected to the network 11 (S402).
Further, the printer searching section 225 acquires information on the printers (the first to third printers 21 to 23) extracted by the searching operation, and causes the storage section 103 to store the acquired information (S403). The information acquired by the searching operation includes the print setup information on the print setup set in the respective printers (the first to third printers 21 to 23), and the printer information containing the information on the function of the respective printers (the first to third printers 21 to 23). The printer searching section 225 causes to store, in the storage section 103, these print setup information and printer information in such a manner that these print setup information and printer information are correlated with the respective printers.
The printer information includes information on a model name and an IP address of the respective printers, a site where the respective printers are positioned. Further, S402 and S403 may be conducted when the PC 10 has a printer driver installed thereon or when a power source of the PC 10 is turned on.
An arrangement of acquiring the print setup information is not limited to the arrangement in which the print setup information is acquired by the searching operation of the printer searching section 225. The PC 10 may acquire a defaulted print setup of the respective printers by installing, via an installer, the printer driver containing the defaulted printer setup.
Subsequently, the print preview creation section 222 creates print preview data corresponding to the respective printers (the first to third printers 21 to 23) (S404).
Subsequently, the display control section 223 causes the display section 104 to simultaneously display the pieces of created print preview data in such a manner that the pieces of created print preview data are arranged in association with the respective printers. At this time, the display control section 223 acquires, from the storage section 103, print setup information on the respective printers capable of outputting (printable) (S405), and reflects the acquired print setup information on respective print preview data (S406).
The following describes in detail processes of the above-described S401 to S406. The PC 10 transmits a query signal to all devices (network devices) connected to the network 11, by means of broadcasting according to a conventionally well-known protocol such as a SNMP. In response to the query signal, the network devices transmit, to the PC 10, information on an IP address, a name, a function and the like of the network devices. A printer corresponding to a shared driver is extracted on the basis of the name of the device among the information transmitted to the PC 10. Subsequently, information on the extracted printer is displayed as shown in FIG. 4.
According to the above-described processes, it is possible to display current print setups of the printers on the print previews corresponding to the printers which print previews are displayed on the display section 104, that is, on the print preview display screen. The printers capable of outputting (printable) are, for example, printers which are turned on and whose print setup information and printer information are acquired as of the searching operation of the printer searching section 225.
In a case where, in S406, the check box 301 is checked to instruct to reflect the print setup of the default printer over all previews, the print setup of the default printer is reflected on the all print previews of the printers.
Specifically, in order to reflect, on the all print previews of the printers, the print setup of the printer (default printer) selected by checking the check boxes 306 to 308 displayed on the print preview display screen, a user checks the check box 301. In a case where the check box 301 is checked, the display control section 223 reflects the print setup of the selected printer on the all print previews corresponding to the printers which all print previews are displayed on the print preview display screen. For example, in a case where the print setup of the selected printer is set to monochrome printing, the all print previews corresponding to the printers which all print previews are displayed on the print preview display screen are monochromatically displayed.
Further, in a case where sort conditions of the first to third printers 21 to 23 are inputted in the input section 303, the display control section 223 sorts the first to third printers 21 to 23 according to the sort conditions, and causes the display section 104 to display, in an order in accordance with a sort result, the print previews 201 to 203 corresponding to the first to third printers 21 to 23. For example, the printer information on the printers which printer information is stored in the storage section 103 is to be sorted.
In a case where a user inputs, on the print preview display screen or the detail preview display screen, an instruction for changing the print setup, the print setup change section 226 changes, according to the instruction of the user, the print setup of the printer whose detail preview is displayed on the detail preview display screen (S407). In this case, the display control section 223 reflects, on the detail preview 324, the print setup updated by the change process.
Thereafter, in a case where a printer is selected on the print preview display screen or the detail preview display screen (S408), the print setup change section 226 reflects, on print setup information on the selected printer, the print setup updated on the print preview display screen or the detail preview display screen. In this case, the print setup change section 226 reads the print setup information stored in the storage section 103 and then changes a print setup of the read print setup information (S409).
The print instruction section 224 creates print data of user determination data, transmits the created print data to a printer selected as a printer to which the created print data is outputted, and instructs the selected printer to print according to a set print setup (S410).
The following describes in detail the print setup change process of S407 with reference to the flowchart of FIG. 7.
According to the present embodiment, a print setup is basically changed on a detail preview display screen. In a case where a user changes a print setup of any one of the printers (the first to third printers 21 to 23), the user checks the check box 306, 307 or 308 corresponding to the printer whose print setup is to be changed, and instructs, by operating the input section 304, to display a detail preview corresponding to the printer. Alternatively, the user does not check the check boxes 306 to 308 but double-clicks, by a pointing device, on the print preview 201, 202 or 203 corresponding to the printer whose print setup is to be changed. In response to the above operation, the display control section 223 causes the display section 104 to display the detail preview display screen shown in FIG. 5.
In a case where a user changes, in terms of a predetermined item shown in the print setup section 323, the print setup of the printer displayed on the detail preview display screen, the user selects the predetermined item shown in the print setup section 323.
In a case where the predetermined item is selected as described above (S510), the print setup change section 226 changes the print setup according to the instruction of the user. That is, the print setup change section 226 reads, from the storage section 103, the print setup information on the printer displayed on the detail preview display screen, and then updates the read print setup information according to the item selected in the print setup section 323 (S511). In this case, the display control section 223 reflects the updated print setup on the detail preview 324.
As described above, the print setup is changed on the detail preview display screen. However, the print setup may be changed on a print preview display screen, on which the print setup section 323 is provided.
The following describes in detail the print setup storage process of S409 with reference to the flowchart of FIG. 8.
In a case where the print setup is changed by the print setup change section 226 in S407 and the check box 321 for instructing to store the print setup is checked on the detail preview display screen shown in FIG. 5 (S601), the print setup storage processing section 227 stores, in the storage section 103, the print setup changed by the print setup change section 226 (S602).
Further, in a case where no instruction for putting a name on the changed print setup and storing the named print setup is inputted in the input section 322, the print setup storage processing section 227 reflects the changed print setup on the print setup information stored in the storage section 103, and then stores the print setup information in the storage section 103. Meanwhile, in a case where the instruction for putting the name on the changed print setup and storing the named print setup is inputted to the input section 322, the print setup storage processing section 227 names and stores the changed print setup separately from the print setup information stored in the storage section 103.
The print setup information stored in the storage section 103 is read by operating the input section 302 displayed on the print preview display screen shown in FIG. 4. In a case where a plurality of print setup information having different names is stored in the storage section 103, a user operates the input section 302 to display the names on the input section 302, and selects one of the names.
Further, the display control section 223 reflects, on the print preview corresponding to the printer whose check box 306, 307 or 308 is checked, the print setup information selected in the input section 302. In a case where the check box 301 is checked, the display control section 223 reflects, on all print previews displayed on the print preview display screen, the print setup information selected in the input section 302. In this manner, the selected print setup information is employed as the print setup information of the user determination data.
It is accordingly possible to store a print setup often used by a user and a print setup often selected by a user, and also possible to easily extract the stored print setups. This allows a user to efficiently set a print setup appropriate for a user's purpose.
As described above, according to the arrangement of the present invention, the print previews corresponding to the printers selectable as a printer to be employed can be simultaneously displayed on the identical display section 104 in such a manner that the print setup information of the printers corresponding to the print previews is reflected on the print previews and the print previews are arranged in association with the printers corresponding to the print previews. This allows a user to see the displayed print previews of the printers and therefore easily select a desired printer as the printer to be employed.
Further, according to the arrangement of the present embodiment, it is possible to, on the print preview display screen (detail preview display screen), easily change the print setup of data selected to be printed and confirm the print preview displayed according to the changed print setup. Further, on the basis of the changed print setup, it is possible to print by use of the selected printer. This allows a user to easily confirm the print previews, change the print setups and print by use of the printers, as a series of operations.
Furthermore, it is possible to reflect, on the print setup stored in the storage section 103, the print setup changed on the print preview display screen (detail preview display screen) and store the resultant print setup in the storage section 103. This makes it possible to easily employ the changed print setup in successive printings.
