Description

The present invention relates to a data processing device, a setting processing method, an information processing device, and a control program capable of further adding an extended function to a plurality of functions that can be realized by a print processing related program.

  Conventionally, as a release form of an installation set of a printer driver from a hardware vendor that manufactures a device such as a printer, there are the following examples.

  For example, there are cases where a device is bundled at the time of shipment, or a case where a user freely downloads and uses a site of each vendor.

  The printer driver released through such a route is used in various environments. However, as the use environment is diversified, there is an increasing demand for realizing a specific function with the printer driver. This tendency is particularly strong in enterprise environments such as large corporations.

  Against this background, printer drivers that realize the addition of this specific function in a plug-in format have recently appeared.

  This plug-in format printer driver function expansion is a method of realizing a function addition by providing a difference module, that is, a plug-in, separately from a printer driver installation set distributed from a printer vendor.

  For example, a module group (plug-in) to be incorporated in the printer driver that controls the output device is determined according to the printing function set by the user. As a result, a technique relating to a data processing device that reduces redundancy, reduces memory shortage, and realizes simplification of printing processing and improvement of printing speed is disclosed (for example, see Patent Document 1).

  In the function expansion system in this plug-in format, in addition to the above example, plug-ins of various functions including security-related functions have been developed, but these different functions are added to the same driver. There is a case of doing. In such an environment, in order to use a plurality of functions added by the user, an additional function unique UI sheet is added to the user interface (UI) of the printer driver to which the user is added, so that the additional function can be provided to the user. May allow setting.

  At this time, when the user changes the setting of the additional function, or when the setting that can be set by the original printer driver is changed, there may be a case where inconsistency occurs between the settings.

  Even when the setting change of the additional function is not realized by the UI, it is considered that inconsistency with other setting values is caused by realizing the additional function.

  In such a case, if an additional function is not added, the printer driver controls the setting change environment (UI) to be provided to the user by the print setting sheet so that no mismatch occurs between the settings. It was. Specifically, only items that can be set can be set according to a user's setting change, and items that cannot be set (items that cause inconsistencies) cannot be set.

In addition, as described above, the process for preventing inconsistency between settings in the print setting in the printer driver is referred to as conflict processing (see Patent Documents 1 and 2 below).
JP 2002-108580 A JP 2001-75758 A

  However, in a data processing environment in which multiple new functions are added to the printer driver in the form of plug-ins, the inconsistency state associated with each function's unique settings cannot be determined sufficiently, and the settings unique to each function are inconsistent. There was a problem such as becoming a state.

  The present invention has been made to solve the above-described problems, and an object of the present invention is to determine whether or not a conflict has occurred between the setting values of the print processing related program and the extended program, and to determine an appropriate conflict. It is to provide a mechanism that can execute processing.

  The data processing apparatus of the present invention that achieves the above object has the following configuration.

A data processing apparatus capable of further adding a plurality of extended functions to a function that can be realized by a print processing related program, and a first conflict processing rule defined according to a dependency relationship established between two or more set values a first rule storage means for storing a function of the print processing related program, the second conflict processing rule determined in accordance with the dependency relationship established between the set value input to said plurality of extensions The first conflict processing rule and the second conflict processing rule are read from the second rule storage means to be stored, the first rule storage means and the second rule storage means, and the read first rule is read. Two settings of the plurality of functions and the plurality of extended functions based on the conflict processing rule and the second conflict processing rule Characterized by comprising a setting adjustment means for adjusting processing settings so that inconsistency does not occur.

  The setting processing method of the present invention that achieves the above object has the following configuration.

First rule storage means for storing a first conflict processing rule determined according to a dependency relationship established between two or more set values, a function of a print processing related program, and an input to the plurality of extended functions And a second rule storage means for storing a second conflict processing rule determined according to the dependency established between the set values to be set, and a plurality of extensions to functions that can be realized by the print processing related program A print setting adjustment method in a data processing apparatus capable of providing a function, wherein the first conflict processing rule and the second conflict processing rule are obtained from the first rule storage unit and the second rule storage unit. Based on the read first read conflict processing rule and the second conflict processing rule, the plurality of functions and the plurality of Characterized by including a setting adjustment step of adjusting process of any two such inconsistency does not occur between setting the set value of the tension function.

  According to the present invention, even in a data processing environment in which a plurality of new functions are added in a plug-in format to a print processing related program (printer driver), it is possible to determine the inconsistency state associated with each added function unique setting. it can.

  In addition, automatic and accurate conflict processing is realized, and even if the settings unique to each function are in an inconsistent state, it is automatically adjusted to a print setting environment that can execute normal printing, and multiple added The print setting for the function can be performed normally.

  Therefore, it is possible to freely construct a print setting environment in which inconsistencies associated with the added function-specific settings are eliminated and an intended print result can be normally obtained.

  Next, the best mode for carrying out the present invention will be described with reference to the drawings.

  FIG. 2 is a diagram showing an example of a memory map of the RAM 2 shown in FIG. This example shows a memory map of the RAM 2 in a state where a predetermined application and a print processing related program are activated and loaded into the RAM 2 on the host computer 3000.

  In FIG. 2, a RAM 206 is loaded with a BIOS 206, an OS 205, an application 201, a print processing related program 204, and related data 203 as shown in the figure, and a free memory area (free memory) 202 is also secured. Yes.

  Thereby, the application 201 and the print processing related program 204 are in an executable state.

  FIG. 3 is a block diagram showing an example of a printer driver expansion system of the host computer 3000 shown in FIG. This example shows a UI-related configuration when a plug-in module is added to the printer driver 307. Hereinafter, an extended system of the printer driver 307 in this embodiment will be described.

  In FIG. 3, the plug-in module includes a UI plug-in 1104 having an extended function of the UI driver 1103 and a graphics plug-in 1106 having an extended function of the graphics driver 1105. Hereinafter, each plug-in module will be described.

  The UI plug-in 1104 is used when a new sheet is added to a print setting sheet (UI) provided to the user by the printer driver 307. Further, it is used to customize various event processes implemented in the UI driver 1103 such as an installation process performed by the UI driver 1103.

  The UI driver 1103 acquires an interface disclosed by the UI plug-in 1104 when a DDI (Device Driver Interface) exported to the system is called. Using the interface of the UI plug-in 1104 acquired by the UI driver 1103, the customization process implemented in the UI driver 1103 is executed by communicating with the UI plug-in 1104.

  On the other hand, the graphics plug-in 1106 is used to intercept DDI processing that is an interface between a GDI (Graphics Device Interface) 1102 and the graphics driver 1105. Alternatively, it is used when processing is added at a specific timing or when print data spool processing is intercepted.

  The DDI exported by the graphics driver 1105 is appropriately called from the GDI 1102 to generate a job. Then, at the initialization timing, the graphics driver 1105 acquires the interface published by the graphics plug-in 1106 and stores it in the RAM 2.

  Using the acquired interface, the processing of the graphics plug-in 1106 corresponding to the DDI is called at the timing when the DDI is called.

  The called graphics plug-in 1106 executes the processing implemented in the plug-in, and returns the processing to the graphics driver 1105 again.

  Here, if the graphics plug-in 1106 has intercepted the processing, the DDI ends the processing, and if the additional processing is implemented, the subsequent processing is continued as it is.

  When the graphics plug-in 1106 intercepts the print data spool processing of the graphics driver 1105, the interface of the graphics plug-in 1106 is called immediately before the print data in the graphics driver 1105 is spooled. Then, the called graphics plug-in 1106 acquires spooled data and executes specific processing. Thereafter, by calling the spool processing function of the graphics driver 1105 again, the graphics driver 1105 is provided with data subjected to specific processing.

  Then, the graphics driver 1105 that has received the data executes a process of actually spooling to the system spooler 1107. As described above, the extended function of the printer driver 307 is realized by mounting the extended function in the plug-in module.

  Next, a memory map in a state where a print processing related program (printer driver) is loaded into the RAM 2 on the host computer 3000 and becomes executable will be described.

  FIG. 2 is a diagram showing an example of a memory map in a state where a print processing related program (printer driver) is loaded into the RAM 2 on the host computer 3000 and can be executed.

  As shown in FIG. 2, a memory map including an application 201, an empty memory 202, related data 203, a print processing related program (hereinafter referred to as a printer driver) 204, an OS 205, and a BIOS 206 is formed in the RAM 2.

  FIG. 4 is a conceptual block diagram showing an example of print processing of various modules of the host computer 3000 shown in FIG. In this example, a configuration between modules in a state where a first plug-in module set 310 and a second plug-in module set 313, which are a plurality of additional functions, are installed in the printer driver 307 is an example.

  As shown in FIG. 4, the first plug-in module set 310 includes a first plug-in module 309 and a conflict processing rule 308 unique to the first plug-in module 309.

  Similarly, the second plug-in module set 313 also includes a second plug-in module 312 and a conflict processing rule 311 unique to the second plug-in module 312.

  In addition, the printer driver 307 before plug-in includes a conflict processing rule 301, an inference engine 302, a conflict manager 303, a state variable list 304, an internal structure 305, and a driver management unit 306.

  In addition, the printer driver 307 of this embodiment has been described as having a stamp function and a bookbinding printing function by incorporating the first plug-in module 309 and the second plug-in module 312 respectively. However, the function added by the plug-in module is not limited to this.

  As a first plug-in, a document management plug-in can be considered. The copy-forgery-inhibited pattern print can be newly input to the printer driver by the copy-forgery-inhibited pattern plug-in, and the document is registered in the server device (not shown) by the document management plug-in (store mode).

  In general, a copying machine has a limit of reproducibility depending on an input resolution for reading minute dots on an original and an output resolution for reproducing minute dots.

  When the background dots of the copy-forgery-inhibited pattern image are formed smaller than the limit of dots that can be reproduced by the copying machine and the dot block of the latent image is formed to be larger than the limit, the image of the large copy-forgery-inhibited pattern image is reproduced by copying. Is done. And the image by a small dot is not reproduced, but a latent image becomes obvious.

  Even if the small dots dispersed by copying do not disappear completely, the latent image can be recognized more remarkably even when the density after copying is lower than that of the concentrated dot cluster. An image in which the image appears in this way is called a visible image. By embedding a visible image such as prohibited copying, it functions as printing for checking copying.

  When copy-forgery-inhibited pattern printing is set, if the document management module allows setting of store printing for registering print data to an external computer, there is a risk that security may be lowered.

  Therefore, it is conceivable that the first plug-in module 309 and the second plug-in module 312 store a rule that prohibits store printing when copy-forgery-inhibited pattern printing is set.

  The conflict manager 303 acquires the conflict rule from the first plug-in module 309 and / or the second plug-in module 312 (307-15). Based on the acquired rule, the conflict manager 303 performs control to prohibit store printing when copy-forgery-inhibited pattern printing is set (307-27).

  Reference numeral 301 denotes a conflict processing rule that defines a rule for preventing inconsistencies between settings in the printer driver 307 before plug-in. A specific example of the conflict processing rule will be described later.

  A conflict manager 303 manages the data in the state variable list 304 and the internal structure 305 so as to match.

  Here, the state variable list 304 is a state variable (for example, Group, Staple, or Collate) corresponding to a setting item (for example, group, staple, sort) that can be set by the printer driver 307 and its value (setting item ON). / Off) list.

  The data in the internal structure 305 is a member (for example, cGroup, cStapple, cCollate) that is a variable corresponding to a setting item (for example, group, staple, sort) that can be set by the printer driver 307 and its value (ON = 1). , OFF = 0).

  An inference engine 302 reads the conflict processing rule 301, the first plug-in conflict processing rule 308, and the second plug-in conflict processing rule 311 via the conflict manager 303. Then, a conflict check (inspection for setting according to the rule) is performed, and the result is returned to the conflict manager 303.

  A driver management unit 306 performs UI display control for performing initialization processing and print settings and operation control in the printer driver 307 in response to a print setting request from the application 201.

  In addition, the driver management unit 306 requests the conflict manager 303 to perform conflict processing so that inconsistencies between settings do not occur.

  The driver management unit 306 also exchanges data with the first plug-in module 309 and the second plug-in module 312.

  Here, a simple specific example of what conflict processing is performed by the conflict manager 303 and the inference engine 302 illustrated in FIG. 4 using the state variable list 304, the internal structure 305, and the conflict processing rule 301 is shown. I will explain.

Figure 5 is a diagram showing an example of the conflict processing in the conflict manager 303 and the inference engine 302 shown in FIG.

  FIG. 5 shows an example in which the conflict manager 303 uses the variable list 304 and the internal structure 305 and the inference engine 302 uses the conflict processing rule 301. Therefore, the state variable list 304 and the internal structure 305 are described in the conflict manager 303, and the conflict processing rule 301 is described in the inference engine 302.

  The specific example shown in FIG. 5 shows an example of conflict processing in accordance with the settings of printer function names A, B, C.

  As shown in FIG. 5, the internal structure 305 has members int cA, cB, cC... Corresponding to printer function names A, B, C... And their values “0”, “1”, “0”. Stored.

  The conflict manager 303 refers to the members of the internal structure 305 and their values to generate a state variable list 304 of state variable A = OFF, state variable B = ON, state variable C = OFF,.

  Since the inference engine 302 refers to the state variable list 304, the initial values of the state values of the printer function names A, B, C... In the inference engine 302 are “OFF”, “ON”, and “OFF”. Become.

The conflict processing rule 301 includes
Assume that the rules A (ON) <-B (ON), C (OFF) are defined.

  This defines a rule that the function A is turned on when the function B is on and the function C is off.

  The inference engine 302 reads the conflict processing rule 301 via the conflict manager 303.

  Here, it is assumed that the inference engine 302 infers the conflict check. Since the initial values are the printer function name B = ON and the printer function name C = OFF, the rules A (ON) <− B (ON) and C (OFF) defined in the conflict processing rule 301 are established.

  As a result, the inference engine 302 changes the state variable value of the printer function name A on the left side to ON. That is, the inference engine 302 updates the state variable list 304 to state variable A = ON.

  In the inference engine 302, after the conflict check inference is completed, the conflict manager 303 reflects the changed value of the state variable A in the corresponding member int cA of the internal structure 305 of the printer driver 307.

  That is, the value of int cA is changed from “0” to “1” when the above rule is satisfied.

  Through the processing as described above, the conflict manager 303 and the inference engine 302 update the state variable list 304 so that no inconsistency occurs between the settings. This is reflected in the setting information (members cA, cB,...) In the internal structure 305 used by the driver management unit 306 for the UI.

  Note that the rules defined in the above-described conflict processing rule 301 are for showing a simple specific example, and the conflict processing rule 301 of the present embodiment includes, for example, rule examples (1) to (3) shown below. ) Is defined.

Collate (OFF) <-Group (ON) (1)
Collate (OFF) <-Staple (ON) (2)
Collate (ON) <-Group (OFF) (3)
Further, the conflict processing rule 308 of the first plug-in defines a rule example (4) as shown below, for example.

Poster (OFF) <-Stamp (ON) (4)
Furthermore, the conflict processing rule 311 of the second plug-in defines a rule example (5) as shown below, for example.

Group (OFF) <-Booklet (ON) (5)
Here, Collate indicates a sort function, Group indicates a group function, Staple indicates a staple function, Stamp indicates a stamp print function, and Booklet indicates a bookbinding print function.

  Next, processing related to the UI of the printer driver 307 in the host computer 3000 of this embodiment will be described.

  When an initialization process provided in the printer driver 307 is called from the application 201 operating under the management of the OS 205, the printer driver 307 is loaded into the RAM 2 under the management of the OS 205.

  When the printer driver 307 is loaded into the RAM 2, the initialization processing unit of the printer driver 307 provided in the driver management unit 306 is called to perform initialization processing.

  FIGS. 6 to 8 are flowcharts showing an example of a first data processing procedure in the data processing apparatus according to the present invention, and performs an initialization process when opening the UI of the printer driver 307 from the application 201 shown in FIG. Corresponds to the procedure. Note that (201-1) to (201-5) correspond to steps executed by the application 201. Also, (307-1) to (307-28) correspond to the steps executed by the driver management unit 306 shown in FIG. Further, (310-1) to (310-10) correspond to the steps executed by the first plug-in module set 310. Further, (313-1) to (313-10) correspond to the steps executed by the second plug-in module set 313.

  The first plug-in module 309 shown in FIG. 6 is incorporated in the printer driver 307 by plug-in as shown in FIG.

  First, the application 201 inquires of the printer driver 307 about the size of the memory area for storing the internal structure of the printer driver 307 (201-1).

  When the printer driver 307 receives the inquiry in step (201-1) (307-1), the printer driver 307 sends the data area of the internal structure that requires the first plug-in module 309 to the first plug-in module 309. The size is inquired (307-2).

  When the first plug-in module 309 receives an inquiry about the size of the data area (310-1), the area size of the necessary internal structure is calculated (310-2), and the calculated area size is set to the printer driver 307. (310-3).

  Thereafter, when the printer driver 307 receives the size of the area calculated by the first plug-in module 309 (307-3), the size of the internal structure necessary for the first plug-in module 309 is acquired (307- 4).

  In the present embodiment, it is assumed that two plug-in modules (first plug-in module 309 and second plug-in module 312) are installed. Therefore, next, the printer driver 307 inquires of the second plug-in module 312 about the size of the data area of the internal structure 305 required by the second plug-in module 312 (307-5).

  Upon receiving an inquiry about the size of the data area (313-1), the second plug-in module 312 calculates the area size of the necessary internal structure 305 (313-2), and calculates the calculated area size to the printer. It returns to the driver 307 (313-3).

  Upon receiving the size of the internal structure required for the second plug-in module 312 (307-6), the printer driver 307 acquires the size of the internal structure required for the second plug-in module 312 (307- 7). After that, the data size obtained by adding the size of the internal structure necessary for the printer driver 307 to the sum of the sizes of the two plug-in modules acquired in steps (307-4) and (307-6) is returned to the application 201 ( Step 307-8).

  The application 201 receives the value returned from the printer driver 307 (201-2), acquires the value returned from the printer driver 307 (201-3), and allocates a memory area for the acquired size in the free memory 202. (201-4).

  Next, the memory area secured in step (201-4) is transferred to the printer driver 307, an instruction is given to the printer driver 307 to open the UI of the printer driver 307 (201-5), and the process is terminated.

  The internal structure 305 at this time has a memory map configuration as shown in FIG. 9, for example.

  FIG. 9 is a diagram showing a memory map configuration example of the internal structure 305 required by the printer driver 307 shown in FIG.

  As shown in FIG. 9, the internal structure 305 includes a public area 601. In addition, a driver private area 602 corresponding to the data area size required for the printer driver 307 is provided. Further, the first plug-in module 309 and the plug-in private area 603 corresponding to the unique data area size of the second plug-in module 312 are configured.

  Next, when an instruction to open the UI of the printer driver 307 is received (307-9), an interface (Document Property) of the printer driver 307 is called based on the received instruction (307-10).

  Then, the printer driver 307 inquires of the first plug-in module set 310 about the storage location of the first conflict processing rule 308 included in the first plug-in module 309 (307-11). .

  Then, an inquiry about the storage location of the first conflict processing rule 308 in which the first plug-in module 309 is bundled is received (310-4). Then, the storage location of the file in which the first conflict processing rule 308 related to the setting value of the first plug-in module 309 is described is returned to the printer driver 307 (310-5).

  Next, the storage location is received from the first plug-in module 309 (307-12). Next, the printer driver 307 inquires about the storage location of the second conflict processing rule 311 included in the second plug-in module 312 (307-13).

  Then, an inquiry about the storage location of the second conflict processing rule 311 in which the second plug-in module 312 is bundled is received (313-4). Then, the second plug-in module 312 returns the storage location of the file in which the second conflict processing rule 311 related to the setting value of the second plug-in module 312 is described to the printer driver 307 (313-5). ).

  The printer driver 307 receives the storage location of the file in which the second conflict processing rule 311 is described (307-14). Then, the inference engine 302 stores the conflict processing rule 308 bundled with the first PM 309 and the conflict processing rule 311 bundled with the second PM 312 in the RAM 2 via the conflict manager 303. Read. Then, the conflict processing rule 301 is read (307-15).

  As described with reference to FIG. 4, all printer function names defined in the conflict processing rules 301, 308, and 311 correspond to the printer function names as shown in FIG. 5 as the state variable list 304. Has a state variable and its value.

  As shown in FIG. 4, the value of the state variable in the state variable list 304 is linked with the value of the corresponding member of the internal structure 305 used in the printer driver 307. The initial values of all the state variables in the state variable list 304 are the initial values of the members of the internal structure 305.

  Then, the printer driver 307 initializes the state variable of the first plug-in via the conflict manager 303 (307-16).

  First, when the printer driver 307 instructs initialization of the state variable of the first plug-in module 309, the printer driver 307 receives the instruction (310-6). Then, the first plug-in module 309 initializes a state variable unique to the first plug-in module (310-7). Thereafter, the state variable in which the first plug-in module 309 is initialized is returned to the printer driver 307.

  When the initialized state variable is received from the first plug-in module 309 (307-17), the printer driver 307 adds it to the state variable list 304 via the conflict manager 303.

  Similarly, when the printer driver 307 instructs initialization of the state variable of the second plug-in module 312 (307-18), the printer driver 307 receives the instruction (313-6). Thereafter, the second plug-in module 312 initializes a state variable unique to the second plug-in module, and then returns the initialized state variable to the printer driver 307 (313-7).

  When the printer driver 307 receives the initialized state variable from the second plug-in module 312 (307-19), the printer driver 307 adds it to the state variable list 304 via the conflict manager 303.

  Thereafter, the printer driver 307 initializes its own state variable (307-20). Next, the printer driver 307 displays the first plug-in unique setting sheet in order to display a setting sheet that is a unique UI of the first plug-in module 309 as shown in FIGS. (307-21).

  The first plug-in module 309 receives an inquiry about information of the first plug-in unique setting sheet (310-8). Thereafter, the first plug-in module 309 generates a unique setting sheet (310-9), returns information of the generated unique setting sheet to the printer driver 307 (310-10), and ends the processing.

  When the information of the unique setting sheet generated from the first plug-in module 309 is received (307-22), the printer driver 307 acquires the setting sheet information unique to the first plug-in module 309 (307- 23).

  Similarly, in order to display a setting sheet, which is a UI unique to the second plug-in module 312 as shown in FIGS. 11A and 11B, information on the second plug-in unique setting sheet is inquired ( 307-24).

  The second plug-in module 312 receives an inquiry for information on the second plug-in unique setting sheet (313-8). Thereafter, the second plug-in module 312 generates a unique setting sheet (313-9), returns information of the generated unique setting sheet to the printer driver 307 (313-10), and ends the processing.

  When the information on the unique setting sheet generated from the second plug-in module 312 is received (307-25), the printer driver 307 acquires the setting sheet information unique to the second plug-in module 312 (307-). 26).

  Next, in the printer driver 307, the inference engine 302 performs a conflict check and updates the state variable list 304. Also, conflict processing such as updating of the internal structure 305 by the conflict manager 303 is performed, and if there is a mismatch between settings, it is corrected (307-27).

  Next, a print setting UI as shown in FIG. 10A is displayed (307-28), and the process is terminated. Specifically, the setting sheet of the first plug-in module 309 and the second plug-in module 312 acquired in steps (307-23) and (307-26) is added together with the setting sheet of the printer driver 307 for printing. Display the settings UI.

  As a result, when a plurality of plug-in modules are added to the printer driver 307 and the system state is changed, the print settings unique to the plug-in are automatically set without any inconsistency with the printer driver settings. . Therefore, when a system that adds an additional function as a plug-in is constructed, the burden of adjusting the setting values before and after the system change is greatly reduced, and the convenience for the user is improved.

  In the present embodiment, when the OS 205 is, for example, WINDOWS (registered trademark), a DEVMODE structure is assumed to be generated as an internal structure described later. The flowcharts shown in FIGS. 6 to 8 or FIGS. 12 and 13 to be described later are executed at the timing when the application 201 generates the DEVMODE structure.

  Furthermore, by storing a history of setting changes for the UI screen in NVRAM or the like, it may be configured so that an operator or a service person can confirm that the UI control has been changed by installing a plug-in or the like.

  10 and 11 are diagrams showing examples of print setting sheets in the data processing apparatus according to the present invention. The print setting sheet which is a UI provided to the user by the printer driver 307 after plug-in by the processing of FIG. An example is shown.

  As shown in FIG. 10A, the setting sheet 80 of the first plug-in module 309 called “setting of plug-in 1” is added to the original setting sheet (page setting and finishing) of the printer driver 307. Further, as shown in FIG. 11B, a setting sheet 90 of the second plug-in module 312 called “setting of plug-in 2” is added.

  The setting sheets 80 and 90 include check boxes (CB) 81 and 91 for the user to set the stamp function on / off and the on-bookbinding printing function on / off.

  In the setting sheet 80 shown in FIG. 10A, the check box 81 is not checked, so that the stamp printing function is off (the state variable is in the initial value state). Further, in the setting sheet 90 of FIG. 11A, the check box 91 is not checked, so that the bookbinding printing function is turned off (the state variable is in an initial value state).

  Here, in the setting sheet 80 in FIG. 10A, the user checks the check box 81 as shown in FIG. 10B, thereby turning on the stamp printing function. In addition, in the setting sheet 90 in FIG. 11A, the user checks the check box 91 as shown in FIG. 11B, thereby turning on the bookbinding printing function.

  Next, as shown in FIG. 10B, after the stamp printing function which is the function of the first plug-in is turned on, the function of the second plug-in is used as shown in FIG. A conflict process when a bookbinding printing function is turned on will be described.

  FIG. 12 is a flowchart showing an example of a second data processing procedure in the data processing apparatus according to the present invention. This example corresponds to the conflict processing procedure when the stamp printing function and the bookbinding printing function which are the functions of the first and second plug-ins as shown in FIGS. 10B and 11B are turned on. .

  Note that (3070-1) to (3070-12) correspond to the steps executed by the driver management unit 306 shown in FIG.

  Also, (3100-1) to (3100-3) correspond to the steps executed by the first plug-in module (PM) 310.

  Further, (3130-1) to (3130-3) correspond to the steps executed by the second plug-in module (PM) 313.

  First, as shown in the UI screen state of FIG. 10 (a) to FIG. 10 (b) displayed on the CRT 10 shown in FIG. The structure 305 and the state variable list 304 are updated (3070-1).

  Next, in response to the UI operation, the conflict processing rule 308 of the first PM 309 read in step (307-15) shown in FIG. 7 is applied. Further, the conflict processing rule 311 of the second PM 312 read in step (307-15) shown in FIG. 7 is applied (3070-2).

  Subsequently, processing for applying the conflict processing rule 301 held by the printer driver 307 main body is performed (3070-3). In response to these conflict processes, the state variables in the state variable list 304 are updated (3070-4). Here, the process corresponding to the operation in which the user checks the check box 91 on the UI screen as shown in FIG. 11B from the UI screen state shown in FIG. 11A is similarly processed. .

  In this embodiment, the processing rules in steps (3070-2) and (3070-3) are applied according to the order read in step (307-15) shown in FIG. .

  In addition, the priority order of the processing rules is determined according to the application order of the plurality of processing rules, and in this embodiment, the conflict processing rule 308 has priority over the conflict processing rule 301. In addition, the conflict processing rule 311 has priority over the conflict processing rule 308.

  If the conflict processing rule 301 is to be prioritized, the conflict processing rule 308 or the conflict processing rule 311 is applied first.

  Although this reading order is not particularly described here, the priority order of the conflict processing rules may be described in an information file or the like, and the conflict processing rules may be read according to the information.

  Here, the conflict processing will be described with a specific example.

  For example, in the internal structure 305 shown in FIG. 4, it is assumed that cCollate, cGroup, cPoster, cStaple, cStamp, cBooklet are members corresponding to the printer function.

  The values before applying the conflict processing rule for each member are as follows immediately before step (3070-1).

cCollate = 0
cGroup = 1
cPoster = 1
cStaple = 0
cStamp = 0
cBooklet = 0
As a result, in the state variable list 304, the state variables Collate, Group, Poster Staple, Booklet and state values corresponding to the above members are as follows.

Collate = OFF
Group = ON
Poster = ON
Staple = OFF
Stamp = OFF
Booklet = OFF
At this time, as for the state of the finishing setting sheet 100 which is a UI provided by the printer driver 307, the check button 104 of the poster function is selected as shown in FIG. The sort function radio button 101 is not selected, and the group function radio button 102 is selected.

  Note that the Stamp remains OFF because the user's operation as shown in FIG. 10B has not yet been performed (before step (3070-1)).

  In such a state, the printer driver 307 receives a change request for changing the setting of the stamp printing function from the application 201 to ON in accordance with step (3070-1).

  As a result, the member cStamp of the internal structure 305 is updated from “0” to “1” as shown below.

cCollate = 0
cGroup = 1
cPoster = 1
cStaple = 0
cStamp = 0
cBooklet = 0
Next, the driver management unit 306 calls the conflict manager 303 and updates the status variable of Stamp in the status variable list from off to on. As a result, the state variable list 304 is as follows.

Collate = OFF
Group = ON
Poster = ON
Staple = OFF
Stamp = ON
Booklet = OFF
Subsequently, in step (3070-2), the inference engine 302 is called to start application of the conflict processing rule.

  First, each printer function name in the inference engine 302 is initialized with the value of each state variable in the state variable list 304.

  Subsequently, the rule example (1) of the conflict processing rule 308 read in step (307-15) is applied, and the state value of the state variable Poster changes from ON to OFF.

  The rule example (1) is a rule defined by Poster (OFF) <-Stamp (ON) as described above.

As a result, the state value of the state variable list 304 is also
Collate = OFF
Group = ON
Poster = OFF
Staple = OFF
Stamp = ON
Booklet = OFF
Updated to

  Since there are no other rules to be applied in the conflict processing rules 301 308 311, the application of the conflict processing rules in the inference engine 302 is completed.

  As described above, the conflict processing is performed according to the setting change performed on the UI by the processing of steps (3070-1) to (3070-3).

  Returning to the flowchart of FIG. 12, the state variable list 304 is updated according to the conflict processing rules 301, 308, and 311 in step (3070-4). After that, the conflict manager 303 updates the internal structure 305 according to the updated state variable list 304 (3070-5).

  Specifically, the member values are as follows.

cCollate = 0
cGroup = 1
cPoster = 0
cStaple = 0
cStamp = 1
cBooklet = 0
Next, the printer driver 307 determines whether or not the state variable of the first plug-in module 309 has been updated in the process of step (3070-4) (3070-6).

  If the printer driver 307 determines that the state variable has been updated (YES in step 3070-6), the printer driver 307 calls the first plug-in module 309 (step 3070-7).

  On the other hand, when the first plug-in module 309 is called from the printer driver 307 (3130-1), the control in the original setting sheet of the plug-in module 309 is controlled (3130-2). Then, the control in the original setting sheet of the plug-in module 309 is updated (3130-3), and the processing is returned to the printer driver 307.

  On the other hand, if it is determined in step (3070-6) that the state variable of the first plug-in module 309 has not been updated (NO in step 3070-6), the printer driver 307 determines the state variable of the second plug-in. Is updated (3070-9).

  Similarly, when the printer driver 307 confirms the end of the update returned from the first plug-in module 309 (step 3070-8), the printer driver 307 determines whether the state variable of the second plug-in has been updated. (3070-9).

  However, in this case, since the state variable of the second plug-in has not been updated, the process proceeds to the next step (3070-11). Then, the control in the setting sheet of the printer driver 307 main body is controlled according to the state variable updated in the step (3070-4) (3070-12), and this process is terminated.

  On the other hand, if it is determined in step (3070-9) that the state variable of the second plug-in has been updated, the second plug-in module 312 is called (3070-10). The steps after the second plug-in module 312 is called will be described later.

  In this way, the conflict process corresponding to the setting change shown in steps (3070-1) to (3070-11) and (3130-1) to (3130-3) is performed. Thereby, the finishing setting sheet 100 before the application of the conflict processing rule is in the UI screen state shown in FIG. 14A, but after the application of the conflict processing rule, the UI screen state shown in FIG. To change.

  That is, the check button 104 of the poster function (the member name of the internal structure is “Poster”) was originally selected in the “finishing” setting sheet 100, but the check button 104 was selected by the application of the conflict processing rule. Has changed to no state.

  Next, a process when the bookbinding function sheet which is the second plug-in function is turned on on the UI screen will be described.

  At this time, as shown in FIG. 11B, the state of the finishing setting sheet 100 that is a UI provided by the printer driver 307 is that the sort function radio button 101 is not selected and the group function radio button 102 is selected. Is the selected state.

  Note that the booklet remains OFF because the user's operation as shown in FIG. 8B has not yet been performed (before step 3070-1).

  In such a state, the printer driver 307 receives a change request for changing the setting of the bookbinding printing function from the application 201 to ON in accordance with step (3070-1). As a result, the member cBooklet of the internal structure 305 is updated from “0” to “1” as shown below.

cCollate = 0
cGroup = 1
cPoster = 0
cStaple = 0
cStamp = 1
cBooklet = 1
Next, the driver management unit 306 calls the conflict manager 303 and updates the state variable of the Booklet in the state variable list from off to on. As a result, the state variable list 304 becomes as follows.

Collate = OFF
Group = ON
Poster = OFF
Staple = OFF
Stamp = ON
Booklet = ON
Subsequently, in step (3070-2), the inference engine 302 is called to start application of the conflict processing rule.

  The rule example (2) of the conflict processing rule 311 previously read in step (307-15) shown in FIG. 7 is applied, and the state value of the state variable Group changes from ON to OFF.

  The rule example (2) is a rule defined by Group (OFF) <-Booklet (ON) as described above.

As a result, the state value of the state variable list 304 is also
Collate = OFF
Group = OFF
Poster = OFF
Staple = OFF
Stamp = ON
Booklet = ON
Updated to

  Next, in step (3070-1), rule example (5) of conflict processing rule 301 is applied, and the state value of state variable Collate changes from OFF to ON.

  The rule example (5) is a rule defined by Collate (ON) <-Group (OFF) as described above. Since there is no other rule to be applied in the conflict processing rules 301, 308, and 311, the application of the conflict processing rule in the inference engine 302 is thus completed.

As a result, the state value of the state variable list 304 is also
Collate = ON
Group = OFF
Poster = OFF
Staple = OFF
Stamp = ON
Booklet = ON
(3070-4).

  As described above, the conflict processing is performed according to the setting change performed on the UI screen by the processing of steps (3070-1) to (3070-4).

  Returning to the flowchart shown in FIG. 12, in step (3070-4), the state variable list 304 is updated according to the conflict processing rules 301, 308, and 311. After that, the conflict manager 303 updates the internal structure 305 according to the updated state variable list 304 (3070-5). Specifically, the member values are as follows.

cCollate = 1
cGroup = 0
cPoster = 0
cStaple = 0
cStamp = 1
cBooklet = 1
Next, the printer driver 307 determines whether the state variable of the first plug-in module 309 has been updated (3070-6). In this case, since the state variable of the first plug-in module 309 is not updated, the process proceeds to the next step (3070-9).

  In step (3070-9), the printer driver 307 determines whether the state variable of the second plug-in module 312 has been updated.

  If the printer driver 307 determines that the state variable has been updated (YES in (3070-9)), the printer driver 307 calls the second plug-in module 312 (3070-10).

On the other hand, a second plug-in module 312 calls the printer driver 307 (3130- 1). Then, the control in the unique setting sheet of the second plug-in module 312 is controlled according to the change of the state variable (3130-2). Then, to update the control of its own configuration sheet of the second plug-in module 312 (3130- 3), returns the process to the printer driver 307, the process ends.

  As a result, the printer driver 307 performs processing shown in the following step (3070-11).

  Note that the processing in the case where the state variable of the second plug-in module 312 has not been updated in step (3070-9) (in the case of NO in step 3070-9) is the description of the previous first plug-in module 309. It is the same.

The printer driver 307, in step (3070-11), receiving a state variable corresponding to the second plug updated in step (3 130 -3). Then, the control in the setting sheet of the printer driver 307 main body is controlled according to the state variable corresponding to the received second plug-in (3070-12), and this processing is terminated.

The printer driver 307, in step (3070-12), updates the controls that are controlled by the printer driver 307 main unit in the configuration sheet, and ends the process of the conflict processing and UI.

  As described above, the conflict processing corresponding to the setting change shown in steps (3070-1) to (3070-12) is performed. As a result, the finishing setting sheet 100 before the application of the conflict processing rule is in the UI screen state shown in FIG. 14B, but after the conflict processing rule is applied, the UI screen state shown in FIG. 14C. To change.

  That is, the radio button 102 of the group function (the internal structure member name is “Group”) is originally selected on the “finishing” setting sheet 100. However, due to the application of the conflict processing rule, the radio button 101 for the sort function (the member name of the internal structure 305 is “Collate”) is selected and changed to the on state.

  The processing as described above is repeatedly executed until the end processing provided in the driver management unit 306 is called by the application 201.

  When the termination process of the printer driver 307 is called from the application 201, the information of the conflict processing rules 301, 308, and 311 generated in the free memory 202 is deleted and other termination processes are performed.

  As a result, the processing is completed, the processing of the printer driver 307 in this embodiment is also completed, and the processing is deleted from the RAM 2 by the function of the OS 205.

  As described above, the host computer 3000 according to the present embodiment prevents inconsistencies between settings in the printer driver 307 after plug-in even if the printer driver 307 includes a plurality of PMs 309 and 312. be able to. That is, by referring to the conflict processing rule 308 of the first PM 309 and the conflict processing rule 311 of the second PM, it is possible to prevent inconsistency between settings in the printer driver 307 after plug-in.

  In other words, the host computer 3000 in the present embodiment can perform accurate conflict processing even in an environment in which a plurality of new functions are added to the printer driver in a plug-in format.

  When the plug-in module is uninstalled, the conflict processing rule file corresponding to the plug-in module is deleted together with the plug-in module.

  Further, when installing the plug-in module, all information related to the plug-in module registered in the registry or the like on the OS running on the host computer 3000 is deleted.

  In the present embodiment, the case where two plug-in modules are installed has been described. Needless to say, the present invention can be applied to the case where two or more plug-in modules are installed.

  In this embodiment, the medium for recording the printer driver 307 is the external memory 11. As the external memory 11, an FD (flexible disk), HD drive, CD-ROM, IC memory card, or the like can be used. is there.

Needless to say, is also included.

For example, a data processing apparatus capable of adding a plurality of extended functions to functions that can be realized by a print processing related program,
First rule storage means (for example, the external unit shown in FIG. 1) that stores as a first conflict processing rule (conflict processing rule 308 shown in FIG. 4) determined according to the dependency relationship established between two or more set values. Memory 11),
Stored as a second conflict processing rule (conflict processing rule 311 shown in FIG. 4) determined in accordance with the dependency established between the function of the print processing related program and the set values input to the plurality of extended functions. Second rule storage means (for example, the external memory 11 shown in FIG. 1);
The first conflict processing rule and the second conflict processing rule are read from the first rule storage means and the second rule storage means, and the read first conflict processing rule and second conflict are read. Based on the processing rule, a setting adjustment unit (printer driver 307 shown in FIG. 3) that performs a setting value adjustment process so that no mismatch occurs between any two settings of the plurality of functions and the plurality of extended functions. And a conflict manager 303).

  Thereby, even in a data processing environment in which a plurality of new functions are added in a plug-in format to the print processing related program (printer driver), it is possible to determine the inconsistency state associated with each function-specific setting. Then, automatic and accurate conflict processing can be realized, and even if the settings unique to each function are in an inconsistent state, it is possible to automatically adjust to a print setting environment capable of executing normal printing. Then, it is possible to freely construct a print setting environment in which print settings for a plurality of added functions can be normally performed and intended print results can be normally obtained.

  In addition, when the plurality of extended functions are added, confirmation means for confirming whether or not the second conflict processing rule is stored in the second rule storage means (of the printer driver 307 shown in FIG. 3). A conflict manager 303) may be provided.

  Accordingly, it is possible to reliably read the second conflict processing rule corresponding to the plug-in module for the added extended function.

  Further, the setting adjustment unit applies the first conflict processing rule and the second conflict processing rule in descending order of priority, and sets any two of the plurality of functions and the plurality of extended functions. Setting adjustment processing may be performed so that no inconsistency occurs.

  Accordingly, inconsistent settings between the setting function of the printer driver and each extended function to be added can be automatically adjusted.

Further, display means for displaying various information (CRT 10 shown in FIG. 1),
Screen display means (printer driver 307 shown in FIG. 3) for displaying on the display means a setting status screen on which the user can visually confirm the setting status of the plurality of functions and the plurality of extended functions; ,
The setting state screen displayed on the display unit by the screen display unit may indicate a setting state after a setting adjustment process by the setting adjustment unit.

  This allows the user to confirm the changed setting state after the setting state in which the settings of the plurality of extended functions and the printer driver are adjusted.

Furthermore, in the setting status screen displayed on the display means by the screen display means,
Each setting of the plurality of functions and the plurality of additional functions can be changed by a user's operation, and when the user changes the setting of one or a plurality of functions or the plurality of additional functions, the setting The adjustment means causes inconsistency between any two settings of the plurality of changed functions and the plurality of extended functions based on the read first conflict processing rule and the second conflict processing rule. It is also possible to perform setting adjustment processing so as not to occur.

  As a result, even if the setting is adjusted by the user to adjust the setting state in consideration of the consistency between the printer driver setting and each function setting, the inconsistency is set. The setting state to be avoided can be displayed.
