  A printer driver and a host computer according to an embodiment of a printer driver and a control apparatus of the present invention will be described below with reference to the drawings.

(About the host computer)
Hereinafter, the configuration of a host computer according to an embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a block diagram showing a hardware configuration of the host computer 10. FIG. 1 shows a printer 30 in addition to the host computer 10.

  The host computer 10 is, for example, a personal computer, and includes a control unit 12, a storage unit 14, controllers 16, 18, and 20, a system bus 22, an input unit 24, and a display unit 26, as shown in FIG. The control unit 12 is realized by a CPU, for example, and plays a role of controlling the operation of the host computer 10.

  The input unit 24 is realized by, for example, a keyboard or a mouse, and is a device that receives input from the user. The controller 16 controls input from the input unit 24. The display unit 26 is realized by a display device such as a liquid crystal display, for example, and is a device that displays an image to the user. The controller 18 controls display on the display unit 26.

  The storage unit 14 is realized by, for example, a hard disk and stores a DEVMODE structure (print setting information) including a plurality of setting items related to printing. The DEVMODE structure will be described below with reference to the drawings. 2 and 3 are diagrams showing the configuration of the DEVMODE structure. FIG. 2 shows the contents of the DEVMODE structure in the standard setting. FIG. 3 shows the contents of the DEVMODE structure in the current setting.

  The DEVMODE structure is print setting information including a plurality of items related to printing. Specifically, the DEVMODE structure includes “original orientation”, “original size”, “output size”, “zoom”, “paper feed tray”, “paper type”, “output method”, “number of copies”, It consists of “sort” and “sort” items.

  “Direction of document” indicates whether the document is conveyed vertically or horizontally. “Original size” indicates the size of the original such as A4 or A3. “Output size” indicates the size of the paper on which the document is printed. “Zoom” indicates a magnification for enlarging or reducing the print image. “Paper feed tray” indicates which tray of the printer 30 is used. “Paper type” indicates whether the paper is plain paper or thick paper. “Output method” indicates a method of outputting a document from a printer. “Number of copies” indicates the number of copies to be printed. “Sort” indicates whether or not to print one copy at a time when printing a plurality of copies of a document. “Sorting” indicates whether or not the output is shifted part by part when printing a plurality of copies.

  The storage unit 14 stores a plurality of types of DEVMODE structures as described above. More specifically, in addition to the DEVMODE structure in the standard setting shown in FIG. 2, the storage unit 14 stores the DEVMODE structure in the current setting (see FIG. 3) obtained by changing the DEVMODE structure in the standard setting by the user. I remember it.

  The storage unit 14 also stores a printer driver for causing the host computer 10 to control print processing executed by the printer 30 in accordance with the DEVMODE structure. The printer driver is a program executed in the control unit 12.

  Here, the DEVMODE structure exists for each printer driver. Therefore, when a plurality of printer drivers are installed in the host computer 10, a plurality of DEVMODE structures are stored in the storage unit 14.

  Further, the storage unit 14 stores printer driver information. The printer driver information includes information related to the printer driver. FIG. 4 is a diagram illustrating an example of printer driver information. As shown in FIG. 4, the printer driver information is composed of items of “name”, “document”, “state”, “comment”, “location”, and “model”.

  “Name” is a name given to the printer driver. “Document” indicates the number of documents waiting to be printed. “Status” indicates the status of the printer 30 controlled by the printer driver (for example, print ready or offline). “Comment” is a column that can be arbitrarily entered by the user for the printer driver. “Location” indicates an installation location of the printer 30 controlled by the printer driver. “Model” is the name of the printer 30 controlled by the printer driver.

  Incidentally, the storage unit 14 stores printer driver information related to printers other than the printer 30 in addition to printer driver information related to the printer driver of the printer 30. That is, the storage unit 14 stores a plurality of printer driver information.

  The printer 30 is a printing apparatus that is connected to the host computer 10 and executes print processing based on an instruction from the host computer 10. The printer 30 may be a laser printer or an ink jet printer. The controller 20 executes communication control processing between the host computer 10 and the printer 30.

  The control unit 12, the storage unit 14, and the controllers 16, 18, and 20 are connected to the system bus 22 and can communicate with each other.

  Next, the software configuration of the printer driver will be described with reference to the drawings. FIG. 5 is a block diagram illustrating a software configuration of the printer driver 40. FIG. 6 is a diagram showing difference information.

  As shown in FIG. 5, the printer driver 40 includes a difference unit 42, a recording unit 44, and a change unit 46.

  The changing unit 46 can change the DEVMODE structure in the reference setting to generate a DEVMODE structure in the current setting. The changing unit 46 can further change the DEVMODE structure in the current setting to generate a DEVMODE structure in the new current setting.

  Further, the difference unit 42 generates difference information (see FIG. 6) regarding the difference between the printer driver information (see FIG. 2) in the reference setting and the printer driver information (see FIG. 3) in the current setting. Specifically, the differences between the printer driver information in the reference setting and the printer driver information in the current setting are items of “zoom” and “paper type”. The item of “zoom” is changed from automatic 100% to arbitrary 80%. The item “paper type” is changed from plain paper to thick paper. Therefore, the difference unit 42 generates difference information indicating that these two items have been changed. However, if the change contents of the two items are described as they are, the difference information becomes long. Therefore, the difference unit 42 generates difference information obtained by shortening the change contents of the changed item. In the present embodiment, as shown in FIG. 6, the difference unit 42 generates difference information having the contents of “Z position 80, cardboard for use”.

  The recording unit 44 records the difference information in FIG. 6 in the printer driver information (see FIG. 4) corresponding to the currently set DEVMODE structure in FIG. Specifically, the recording unit 44 records “Z 80, cardboard” as difference information in the “comment” item of the printer driver information.

(Host computer operation)
The operation of the host computer 10 will be described below with reference to the drawings. FIG. 7 is an example of a list screen displayed on the display unit 26 based on the printer driver information.

  The printer driver described in Patent Literature 1 compares the print initial setting content with the current print setting content, and generates print difference content indicating the difference therebetween. Then, as shown in FIG. 13, the printer driver displays the print difference content as a setting changed from the initial setting on the property screen. Accordingly, the user can efficiently check the difference between the current print setting content and the print initial setting content.

  However, with the printer driver described in Patent Document 1, it is possible to confirm at a glance the difference between the current print settings and the initial print settings, but many operations are required to display a screen on which the difference can be confirmed. More specifically, in the printer driver described in Patent Document 1, after the print screen attached to the application is displayed, the printer driver is started by operating the print screen, as shown in FIG. Display the property window of the printer driver. Further, by clicking a setting confirmation tag on the property screen, it is possible to confirm a difference between the current print setting contents and the print initial setting contents.

  Therefore, in the host computer 10, the control unit 12 causes the display unit 26 to display the difference information in the list screen (see FIG. 7) including the printer driver information. At this time, the control unit 12 does not use the UI (user interface) of the printer driver 40 for displaying the list screen, but instead installs the OS installed in the host computer 10 (for example, Windows (registered trademark) of Microsoft Corporation). ) UI. In Windows (registered trademark), the list screen is a screen named “Printer and FAX” displayed by clicking “Start”, “Setting”, and “Printer and FAX”. Thereby, the user can confirm the content of the difference information by confirming the item of “comment” on the list screen. FIG. 8 is a setting screen displayed by the UI of the printer driver 40 in the reference setting. FIG. 9 is an editing screen for setting how to record the difference information. FIG. 10 is a setting screen displayed by the UI of the printer driver 40 in the current setting.

  First, the printer driver 40 displays the setting screen of FIG. The user sets each item of the DEVMODE structure in the reference setting by operating the input unit 24 on the setting screen of FIG. The user operates the input unit 24 and clicks an “add” button next to “favorite”. In response, the printer driver 40 causes the display unit 26 to display the editing screen illustrated in FIG. 9 using the UI.

  On the editing screen of FIG. 9, the user operates the input unit 24 to input “double-sided” as the name of the DEVMODE structure in the standard setting in the “name” item of “add to favorites”. Then, the user operates the input unit 24 to check the “set to reference setting” check box under the “name” item on the editing screen. Furthermore, the user operates the input unit 24 and clicks the “Add” button below the check box, so that “double-sided” that is the name of the DEVMODE structure is displayed in the “Add to Favorites” item. Added. Since the check box for “set to reference” is checked, a circle is added next to “both sides”. The circle indicates that the “double-sided” DEVMODE structure is selected as the default DEVMODE structure.

  Next, the user describes how to record, in the printer driver information, the difference information between the standard setting DEVMODE structure and the current setting DEVMODE structure obtained by changing the standard setting DEVMODE structure later. Edit on the editing screen of FIG. Specifically, a check box “Reflect the name of the reference setting” exists in the editing screen. “Reflect the name of the reference setting” is a check box for determining whether or not to record the name “both sides” of the DEVMODE structure set in the reference setting in the printer driver information of FIG. Therefore, the user operates the input unit 24 to check the “Reflect reference setting name” checkbox. As a result, the radio box for selecting “reflect on driver name” or “reflect on comment” is selectable. “Reflect the driver name” means that the name “double-sided” of the DEVMODE structure of the standard setting is recorded after the name of the printer driver 40 as shown in FIG. “Reflect in the comment” means that the name “double-sided” of the DEVMODE structure of the standard setting is recorded in the comment item. In the editing screen shown in FIG. 9, the “Reflect to driver name” radio box is selected.

  Furthermore, a check box “Reflect the difference between the reference setting and the current setting” exists in the editing screen. “Reflect the difference between the reference setting and the current setting” is a check box for determining whether or not to record the difference information shown in FIG. 6 in the printer driver information of FIG. Therefore, the user operates the input unit 24 and checks the check box “Reflect the difference between the reference setting and the current setting”. As a result, the radio box for selecting “reflect on driver name” or “reflect on comment” is selectable. “Reflect to the driver name” means that the difference information shown in FIG. 6 is recorded after the name of the printer driver 40. “Reflect in a comment” means that the difference information shown in FIG. 6 is recorded in the comment item, as shown in FIG. In the editing screen shown in FIG. 9, the “Reflect in comments” radio box is selected. When the input on the editing screen is completed, the user operates the input unit 24 and clicks an “OK” button at the bottom of the editing screen. As a result, the printer driver 40 stores the settings on the editing screen in the registry of the storage unit 14.

  Next, the user sets the DEVMODE structure in the current setting by operating the input unit 24 on the setting screen of FIG. Note that the setting of the DEVMODE structure in the current setting may be performed immediately after the editing screen of FIG. 9 is closed, or may be performed at the time of print processing or the like. In the setting screen of FIG. 10, the user changes the “zoom” item to an arbitrary 80% and changes the “paper type” item to cardboard on the setting screen of the DEVMODE structure in the reference setting shown in FIG. It has changed. When the setting of the DEVMODE structure in the current setting is completed, the user operates the input unit 24 and clicks the “OK” button at the bottom of the editing screen. In response, the changing unit 46 (see FIG. 5) of the printer driver 40 changes the DEVMODE structure in the standard setting shown in FIG. 2 to the DEVMODE structure in the current setting shown in FIG. . Thereafter, the host computer 10 generates and records the difference information shown in FIG. Hereinafter, generation of difference information will be described with reference to the drawings. FIG. 11 is a flowchart illustrating processing performed by the printer driver 40 executed by the control unit 12 when generating / recording difference information.

  The printer driver 40 determines whether or not to reflect the name of the DEVMODE structure in the standard setting in the printer driver information (step S1). Specifically, the printer driver 40 refers to the registry of the storage unit 14 and determines whether or not the “Reflect reference setting name” check box on the editing screen in FIG. 9 is checked. When reflecting the name in the reference setting, the process proceeds to step S2. If the name in the reference setting is not reflected, the process proceeds to step S5.

  When reflecting the name in the reference setting, the printer driver 40 determines whether or not to reflect the name of the DEVMODE structure in the reference setting in the “name” item of the printer driver information (step S2). Specifically, the printer driver 40 refers to the registry in the storage unit 14 and determines whether or not the “Reflect to driver name” radio box on the editing screen in FIG. 9 is checked. In the case of reflecting in the “name” item, the process proceeds to step S3. If not reflected in the “name” item, the process proceeds to step S4.

  When reflecting in the “name” item, the recording unit 44 of the printer driver 40 reflects the name of the DEVMODE structure in the standard setting in the “name” item of the printer driver information (step S3). Specifically, as shown in FIG. 4, the recording unit 44 has a DEVMODE structure in the standard setting after “**** C450 PCL” input in the “name” item of the printer driver information. Record the name “(both sides)”. Thereafter, the process proceeds to step S5.

  If not reflected in the “name” item, the recording unit 44 (see FIG. 5) of the printer driver 40 reflects the name of the DEVMODE structure in the standard setting in the “comment” item of the printer driver information (step). S4). Specifically, the recording unit 44 records “(both sides)”, which is the name of the DEVMODE structure in the standard setting, in the “comment” item. Thereafter, the process proceeds to step S5.

  In step S5, the printer driver 40 determines whether or not to reflect the difference between the DEVMODE structure in the reference setting and the DEVMODE structure in the current setting in the printer driver information (step S5). Specifically, the printer driver 40 refers to the registry in the storage unit 14 and determines whether or not the “Reflect the difference between the reference setting and the current setting” check box on the editing screen in FIG. 9 is checked. To do. If the difference is reflected in the printer driver information, the process proceeds to step S6. If the difference is not reflected in the printer driver information, this process ends.

  When the difference is reflected in the printer driver information, the difference unit 42 (see FIG. 5) of the printer driver 40 extracts the difference between the DEVMODE structure in the reference setting and the DEVMODE structure in the current setting (step S6). The items of “zoom” and “paper type” are different between the DEVMODE structure in the reference setting shown in FIG. 2 and the DEVMODE structure in the current setting shown in FIG. Therefore, the difference unit 42 determines that the difference between the two DEVMODE structures is that “zoom” is an arbitrary 80% and “paper type” is cardboard.

  Next, the difference part 42 produces | generates difference information based on the extracted difference (step S7). Specifically, the difference unit 42 determines that the difference is “Zoom 80,” as shown in FIG. 6 because the “zoom” is an arbitrary 80% and the “paper type” is cardboard. Difference information having the content of “thick paper” is generated. Thereafter, the process proceeds to step S8.

  Next, the printer driver 40 determines whether or not to reflect the difference information in the “comment” item of the printer driver information (step S8). Specifically, the printer driver 40 refers to the registry of the storage unit 14 and determines whether or not the “Reflect to comment” radio box on the editing screen in FIG. 9 is checked. When reflecting in the item of “comment”, the process proceeds to step S9. If not reflected in the “comment” item, the process proceeds to step S10.

  When reflecting in the “comment” item, the recording unit 44 of the printer driver 40 (see FIG. 5) reflects the difference information in the “comment” item of the printer driver information (step S9). Specifically, as shown in FIG. 4, the recording unit 44 records “Z 80, cardboard”, which is difference information, in the “comment” item of the printer driver information. Thereafter, this process ends.

  If not reflected in the “comment” item, the recording unit 44 of the printer driver 40 reflects the difference information in the “name” item of the printer driver information (step S10). Specifically, the recording unit 44 adds “Z option 80, cardboard” as the difference information after “*** C450 PCL” input in the “Name” item of the printer driver information. Record. Thereafter, this process ends.

  Thereafter, the user operates the input unit 24 to display the list screen shown in FIG. When the OS installed on the host computer 10 is Microsoft Windows (registered trademark), the user operates the input unit 24 to select “Start”, “Setting”, and “Printer and FAX”. click. In response, the control unit 12 uses a Windows (registered trademark) UI to list information on a plurality of printer drivers based on the printer driver information of the printer 30 and the printer driver information of printers other than the printer 30. The displayed list screen (see FIG. 7) is displayed on the display unit 26. Accordingly, the user can understand that the name of the DEVMODE structure in the reference setting is “double-sided”, and can also understand that the difference information is “Z 80, cardboard”.

(effect)
According to the host computer 10 as described above, the difference between the DEVMODE structure in the reference setting and the DEVMODE structure in the current setting can be confirmed with a simple operation. More specifically, in the printer driver described in Patent Document 1, the printer driver is started before the property screen (see FIG. 13) for confirming the difference between the print current setting content and the print initial setting content is displayed. Many operations are required.

  On the other hand, in the host computer 10, the difference information shown in FIG. 6 is described on the list screen shown in FIG. The list screen is a screen on which a list of information related to a plurality of printer drivers is written, and is a screen displayed using the UI of the OS installed in the host computer 10. Therefore, in the host computer 10, unlike the printer driver described in Patent Document 1, the user does not need to activate the printer driver and display the printer driver property screen. For example, when the OS is Windows (registered trademark), the user operates the input unit 24 to display the list screen simply by clicking “Start”, “Settings”, and “Printers and FAX”. be able to. Therefore, according to the host computer 10, the difference between the DEVMODE structure in the reference setting and the DEVMODE structure in the current setting can be confirmed with a simple operation.

(Other embodiments)
The host computer 10 configured as described above is not limited to that described in the embodiment. Therefore, the design of the host computer 10 may be changed within the scope of the gist.

  In the embodiment, the DEVMODE structure in the current setting is obtained by changing the DEVMODE structure in the reference setting. However, the DEVMODE structure in the current setting may not be obtained by directly changing the DEVMODE structure in the reference setting. The DEVMODE structure in the current setting may be obtained by further changing the DEVMODE structure obtained by changing the DEVMODE structure in the reference setting.

  In the embodiment, the DEVMODE structure in the standard setting is a DEVMODE structure set by the user. However, the DEVMODE structure in the reference setting may be a DEVMODE structure prepared in advance when the printer driver 40 is initially set. In this case, the DEVMODE structure in the reference setting corresponds to the initial setting of the DEVMODE structure in the current setting.

  In the embodiment, the difference information is recorded in the “name” or “comment” item of the printer driver information. However, the difference information may be recorded, for example, in the item “location” of the printer driver in the printer driver information.

  In the embodiment, the difference information is displayed on the list screen shown in FIG. 7, but may be displayed on other screens. FIG. 12 is a print screen of an application executed on the host computer 10. The print screen of FIG. 12 is a screen displayed by the UI of the application at the time of print processing such as text creation software. When the print screen of FIG. 12 is displayed, the control unit 12 refers to the printer driver information shown in FIG. 4 and displays the printer name to which the name of the currently set DEVMODE structure is added. The comment in which the difference information shown in is described is displayed. When the properties of the print screen are clicked, the printer driver 40 is activated, and the printer driver 40 setting screen (see FIGS. 8 and 10) is displayed. Therefore, the print screen can be displayed with fewer operation procedures than the setting screen of the printer driver 40. From the above, the user can confirm the difference between the DEVMODE structure in the standard setting and the DEVMODE structure in the current setting.

  The present invention is useful for a printer driver and a control device, and is particularly excellent in that a difference between the reference print setting information and the current print setting information can be confirmed with a simple operation.
