JP6465403B2 - Printer driver update program and printer driver update method - Google Patents

Description

  The present invention relates to a printer driver update program and a printer driver update method, and more particularly to a printer driver update program and a printer driver update method for updating a printer driver according to a user's usage environment.

  In a system in which a client device and a printer are connected via a network, when the client device instructs printing to the printer, a printer driver corresponding to the printer is installed and registered in the client device, and the printer driver can be used A print instruction is given using an icon (also called a print queue).

  A client device can also be configured by setting a predetermined computer device connected to the network as a server device, installing and registering a printer driver in the server device, and sharing a printer icon for enabling the printer driver on the network. A print instruction can be given to the printer.

  Also, when multiple types of printers are connected on the network, the client device and the server device must manage printer drivers for each model (referred to as model-specific printer drivers), which makes management complicated. In recent years, a common printer driver (referred to as Universal Printer Driver (UPD)) corresponding to a plurality of types of printers has been put into practical use.

  A new version of this UPD is released every time a new model or a new function is added. The UPD update operation is mainly performed by the IT administrator, and the IT administrator confirms whether the UPD operates normally after the update. For example, a test print or an actual operation is performed to confirm whether printing is performed correctly. Therefore, in an environment where multiple types of printers are used, installing UPD to support the new model will also update the printer driver corresponding to the currently used model. Confirmation is required, and confirmation man-hours increase.

  Therefore, in order to reduce the confirmation man-hours, it is possible not only to “update” the UPD to the latest version but also to add the latest version to “coexist” with the current version. A method has been proposed that allows the user to select whether to coexist. For example, the following Patent Document 1 discloses a printer driver update program for updating a printer driver capable of controlling a plurality of types of printers, and a new version of the module for realizing a predetermined function of the printer driver. One of the overwriting process for overwriting the old version program already existing in the printer driver and the additional process for adding the new version program to the printer driver separately from the old version program Disclosed is a printer driver update program that causes a computer to execute a procedure (a) for selecting the process (a) and a procedure (b) for updating the printer driver by executing the process selected in the procedure (a). Has been.

  In the printer driver update program with such a configuration, the user selects “coexistence” and only the new model printer uses the latest version of UPD, so the confirmation corresponding to the currently used model becomes unnecessary. The confirmation man-hour can be reduced.

JP 2012-043161 A

  Here, the UPD may be updated not only to add new models and new functions, but also to correct defects in existing models and existing functions. In such a case, it is necessary to refer to technical information such as release notes when selecting whether to “update” the currently used model or function. There is a problem that it is not possible to easily select “coexistence”. In addition, if “coexistence” is selected every time the UPD is updated, there is a problem that the file size of the installed driver increases.

  The present invention has been made in view of the above problems, and a main object thereof is to provide a printer driver update program and a printer driver update method capable of easily and appropriately updating the UPD.

  According to one aspect of the present invention, a printer driver that can control a plurality of types of printers is installed, and the printer driver that operates on a device that operates the printer driver based on a printer icon that designates an output destination printer is installed. A printer driver update program for updating to a newer version than the current version that has been completed, wherein the device acquires update information relating to the updated contents of the printer driver of the new version and records it in association with each printer icon An information acquisition unit for acquiring setting information and usage history information relating to the output destination printer, comparing the update information with the setting information and the usage history information, and for each printer icon, a new version of the printer Update to the driver is required A determination unit that determines whether or not each printer icon needs to be updated, a determination result display unit that displays a screen indicating whether update is necessary for each printer icon, and an update processing unit that updates the printer driver according to the conditions instructed on the screen It is characterized by functioning as.

  According to one aspect of the present invention, a printer driver capable of controlling a plurality of types of printers is installed, and the printer driver is installed in an apparatus that operates the printer driver based on a printer icon in which an output destination printer is designated. A printer driver update method for updating to a newer version than the current version, wherein the output destination acquires update information regarding the update contents of the printer driver of the new version and is recorded in association with each printer icon The information acquisition process for acquiring the setting information and usage history information about the printer is compared with the update information and the setting information and the usage history information, and the update to the new version of the printer driver is performed for each printer icon. Determine whether it is necessary A determination process, a determination result display process for displaying on the display unit a screen indicating whether or not each printer icon needs to be updated, and an update process for updating the printer driver according to the conditions instructed on the screen are executed. It is characterized by that.

  According to the printer driver update program and the printer driver update method of the present invention, UPD can be updated easily and appropriately.

  The reason is that a printer driver update program for updating a printer driver (UPD) capable of controlling a plurality of types of printers acquires update information of a new version of UPD to be installed and supports each printer icon. The setting information and usage history information recorded together are acquired, the update information is compared with the setting information and usage history information, and it is determined whether an update to a new version is necessary for each printer icon, and the determination result This is because the display is controlled.

FIG. 9 is a flowchart illustrating processing of a printer driver update program (in the case of updating some printer icons) according to an embodiment of the present invention. FIG. 11 is a flowchart illustrating processing of a printer driver update program according to an embodiment of the present invention (when all printer icons are not updated).

  As shown in the background art, UPD corresponding to a plurality of types of printers has been put into practical use. In UPD, since the latest version is released to add a new model or a new function, there is a problem that it takes time to check the operation. To solve this problem, a method has been proposed in which it is possible to select whether to update the UPD to the latest version or add the latest version to “coexist” with the current version.

  However, updating the UPD includes not only the addition of new models and new functions, but also the handling of defects in existing models and existing functions. It is not easy to choose what to do. If “coexistence” is selected every time the UPD is updated, the file size of the UPD increases.

  Therefore, in one embodiment of the present invention, the printer driver update program (installer) for UPD determines whether or not an update to a new version of UPD is necessary according to the usage status of each printer icon. The determination result is displayed. For example, if the new version of UPD is only a model or function update that the user does not use, the user is notified that the update is not required, and the user appropriately determines whether to update or coexist. To be able to select.

  Specifically, the UPD holds update information, and when the UPD is installed, the output destination printer is designated and registered (in the printer icon), the setting information and the usage history status regarding the output destination printer are used. Stored as status information. When the user activates the printer driver update program, the printer driver update program obtains and compares the update information of the new version of the UPD and the usage status information of each printer icon, and compares each printer icon with the new version of the UPD. If it is determined that updating is necessary, “update recommended” is notified to the user, and if it is determined that updating is not necessary, “update not required” is notified to the user. If the total UPD file size when the current version and the new version coexist is compared with the preset upper limit value of the file size, and the total UPD file size is larger than the upper limit value, , “Update recommendation” is notified to the user.

  In this way, when a new version of UPD is an update for a model or function that the user does not use, the user can use the printer icon in the existing version to notify the user that the update is not necessary. Can be eliminated and the number of confirmation steps can be reduced. In addition, if the total UPD file size when the current version and the new version coexist is larger than the upper limit, updating is recommended, so the burden on the computer device due to the increase in the UPD file size is reduced. can do.

  In order to describe the above-described embodiment of the present invention in more detail, a printer driver update program and a printer driver update method according to an embodiment of the present invention will be described with reference to FIGS. FIG. 1 is a diagram schematically illustrating a configuration of a printing system according to the present exemplary embodiment, FIG. 2 is a block diagram illustrating a configuration of a client device, and FIG. 3 is a block diagram illustrating a configuration of a printer. 4 is an example of a printer icon, and FIGS. 5, 10-12, and 14 are diagrams illustrating an example of a screen displayed on the client device of the present embodiment. 6 is a table showing UPD update information, FIGS. 7 and 13 are diagrams showing examples of printer icon usage status information, and FIGS. 8, 9, and 15-17 are examples of this table.

  The UPD 18 can issue a print instruction to a plurality of types of printers 30, and includes a printer driver (referred to as a child driver) corresponding to each type of printer 30 and a management unit that manages the plurality of printer drivers. Composed. When the UPD 18 is installed and the printer 30 on the network is designated and registered, a printer icon (instruction information for making the UPD 18 corresponding to a predetermined printer available) is generated. The UPD 18 corresponding to the desired printer 30 is operated by the printer icon, and the UPD 18 uses a language (PCL (Printer Control Language) or PSL) in which the printer 30 can interpret document data created using the application 17. Print data is created by converting it into PDL (Page Description Language) such as (Post Script), and the print data is transmitted to the printer 30 to instruct printing.

  The UPD 18 holds update information related to version update contents. For example, the new version UPD 18 holds update information related to update contents from the previous version (or the previous version) UPD 18 (for example, held in a predetermined file in a file group for installing the UPD 18). Further, the UPD 18 can record (for example, record in a file that can be referred to by the program) the setting information of each printer icon (the model of the output destination printer 30, the function provided in the printer 30, etc.). Further, when a print instruction is issued using each printer icon, usage history information such as which function of the printer 30 is used and what kind of file is used is recorded (for example, a program can be referred to). Can be recorded in a simple file). The setting information and usage history information are collectively referred to as usage status information.

  The printer driver update program 19 is a program (installer) for updating the UPD 18 (installing a new version of the UPD 18). The printer driver update program 19 may include a file group for installing a new version of the UPD 18 and install the UPD 18 using the file group, or a predetermined storage unit (for example, on the Internet).

In addition, the information acquisition unit 19a acquires usage status information recorded for each printer icon from a file or the like that is referenced by the UPD 18 of the current installed version (hereinafter referred to as an old version). Further, the information acquisition unit 19a acquires the file size information of the UPD 18 (the total file size value obtained by adding the file size of the installed previous version UPD 18 and the predicted file size of the new version UPD 18 to be installed). In addition, an upper limit value of the file size set in advance by the user is acquired.

  The determination unit 19b compares the update information acquired by the information acquisition unit 19a with the usage status information of each printer icon, determines whether it is necessary to update the new version UPD 18 for each printer icon, and determines whether the printer icon Whether the old version UPD 18 and the new version UPD 18 coexist, updated to the new version UPD 18 (the old version UPD 18 is deleted), or not updated to the new version UPD 18 based on the necessity for each update It is determined which is applicable. When the old version UPD 18 and the new version UPD 18 coexist, the file size total value of the old version UPD 18 and the new version UPD 18 is compared with a preset upper limit value, and the file size total value is the upper limit. If it becomes larger than the value, it is recommended to update to the new version of UPD18.

  The determination result display unit 19c displays the determination result made by the determination unit 19b on the display unit 14. For example, the necessity of updating for each printer icon is displayed on a determination result display screen described later, or a list of necessity of updating all printer icons is displayed on a determination result detail display screen described later. Further, the determination result display unit 19c displays on the determination result display screen such that the necessity of coexistence between the old version and the new version can be specified, and specifies the determination result of the determination unit 19b by default.

  The update processing unit 19d executes the update process of the UPD 18 under the conditions specified by default on the determination result display screen and the determination result detail display screen or the conditions specified by the user. Further, the update processing unit 19d updates the setting information and display form of the printer icon corresponding to the updated UPD 18. Also, the update processing unit 19d sets restriction information for the model and function and version information of the new version UPD 18 on the printer icon that uses the defective model and function, and the UPD 18 displays a print setting screen described later. In such a case, it is possible to display a message indicating that a defective function cannot be selected, or to display a message indicating that a new version needs to be installed.

  The storage unit 12 includes an HDD (Hard Disk Drive), an SSD (Solid State Drive), and the like, and stores programs, print data, and the like. In this embodiment, in particular, update information of the UPD 18, usage status information of each printer icon, an upper limit value of the file size of the UPD 18, and the like are stored.

However, when the UPD 18 is installed in the server device 20, the printer icon may be set to be shared so that the client device 10 can use the printer icon. In this embodiment, the UPD 18 is provided with a function of recording the usage status information of each printer icon. However, any resident program may have a function of storing the usage status information of the printer icon. Good.

[Printer]
As shown in FIG. 3, the printer 30 includes a control unit 31, a storage unit 32, a communication I / F unit 33, a display / operation unit 34, an image reading unit 35, an image processing unit 36, and a printing process. The unit 37 and the post-processing unit 38 are included.

  The control unit 31 includes a CPU and a memory such as a ROM or a RAM. The CPU reads various programs from the ROM or the storage unit 32, expands and executes them in the RAM, and controls the operation of the entire printer 30.

  The storage unit 32 is configured by an HDD, an SSD, or the like, and stores programs, print data, image data processed by the image processing unit 36, and the like.

  The communication I / F unit 33 is configured by a NIC, a modem, or the like, and receives print data from the client device 10 or the server device 20 via a communication network.

  The display / operation unit 34 includes a pressure-sensitive operation unit (touch panel) in which transparent electrodes are arranged in a lattice pattern on a display unit such as a liquid crystal display device or an organic EL display device, and a screen for operating the printer 30. And a screen for setting printing conditions, and various settings and instructions are made possible.

  The image reading unit 35 is a part that optically reads image data from a document on a document table, such as a light source that scans the document and a CCD (Charge Coupled Devices) that converts light reflected by the document into an electrical signal. An image sensor and an A / D converter for A / D converting electrical signals are used.

  The image processing unit 36 analyzes the print data, rasterizes each page of the print data to generate image data for each page, or acquires image data for each page from the image reading unit 35, and if necessary, After processing (color adjustment, density adjustment, size adjustment, etc.) and screening, the print processing unit 37 converts the image data into printable image data.

  The print processing unit 37 includes constituent elements necessary for image formation using an image forming process such as an electrophotographic method or an electrostatic recording method. A print image based on the image data created by the image processing unit 36 is displayed as setting information. Print on the paper specified in.

  The post-processing unit 38 performs post-processing such as stapling, punching, and folding on the paper conveyed from the print processing unit 37 in accordance with an instruction from the control unit 31 and outputs the result.

  FIG. 3 shows an example of the printer 30 of this embodiment, and the configuration thereof can be changed as appropriate. For example, in this embodiment, the image processing unit 36 is provided in the printer 30 and the print data is acquired from the client device 10 or the server device 20. However, a controller or the like having a RIP (Raster Image Processor) unit in the communication network is used. The controller may receive the print data transmitted from the client device 10 or the server device 20, rasterize the print data to generate image data, and transmit the generated image data to the printer 30.

  Next, update processing of the UPD 18 using the printing system having the above configuration will be described. In the following description, it is assumed that the UPD 18 is installed in the client device 10 and the printer driver update program is operated on the client device 10.

  FIG. 4 is an example of the printer icon 18a displayed on the display unit 14 when the UPD 18 is installed in the client device 10 and the printer 30 is designated and registered. The printer icon 18a can be registered not only for each printer 30 to be used, but also for a plurality of printer icons with changed connection methods and function settings. For example, with respect to the printer A in FIG. 1, a printer connected via a TCP (Transmission Control Protocol) / IP (Internet Protocol) port is “printer A-1”, and a printer connected via USB is “printer A-”. 2 ”, a printer that is connected with a TCP / IP port and changes the monochrome to the default can be registered as a“ printer A-3 ”.

  When the user instructs printing on the screen of the application 17 after registering the printer icon 18a, the UPD 18 is activated in response to the printer icon 18a, and the UPD 18 displays on the display unit 14 the printer 30 designated by the printer icon 18a. A print setting screen for setting print conditions is displayed. FIG. 5 is an example of the print setting screen 40. On the print setting screen 40, functions that can be set by the printer 30 are classified and displayed by tabs. For example, multiple settings for setting functions such as “paper size”, “single-sided / double-sided”, “page allocation”, which are basic settings related to printing, and “staple”, “page unit setting” related to post-processing Items are displayed, and the user operates the operation unit 15 to set each setting item in accordance with the purpose of printing.

  When the user selects the OK button on the print setting screen 40 to instruct printing, the UPD 18 converts the document data created by the application 17 into print data that can be interpreted by the printer 30, and changes the print conditions to the print data. Describe and output to the printer 30. When the printer 30 receives the print data, the image processing unit 36 analyzes the print data, the print processing unit 37 executes printing in accordance with the printing conditions described in the print data, and the post-processing unit 38 displays the print data. The post-processing is executed according to the post-processing conditions described in 1.

  FIG. 6 is an example of update information of the UPD 18. The UPD 18 of the present embodiment holds update information indicating what kind of update has been made during version upgrade. The example of FIG. 6 shows update information in Ver.1.1, and holds version, update type, target model, target function, target file, and the like. There are three types of update: “model addition”, “function addition”, and “defect handling”.

  “Add model” indicates that a new model is available. When the user uses a new model, it is necessary to update the UPD 18 (install a new version of the UPD 18). If the user does not use a new model, the UPD 18 need not be updated.

  “Addition of function” indicates that an existing model registered in the UPD 18 corresponds to a new function by updating the main body FW (firmware). When the user uses the function, the UPD 18 needs to be updated. If the user does not use a new function, the UPD 18 need not be updated.

  “Failure handling” indicates that a bug that has occurred in the current version of UPD 18 has been corrected, and information on the model, function, and target file type in which the bug has been corrected is held. When the user uses the model, function, and file type, the UPD 18 needs to be updated. If the user does not use the model, function, and file type, the UPD 18 need not be updated.

  FIG. 7 is an example of printer icon usage status information. The UPD 18 of this embodiment records usage status information including setting information and usage history information for each printer icon. Here, the version of UPD18 corresponding to the printer icon (here, Ver.1.0), the functions that can be set in the model, the usage history of each function (used or not used), the type of file printed, etc. are recorded. Is done.

  Next, processing of the printer driver update program in the client device 10 (or server device 20) will be described. The CPU executes the process of each step shown in the flowcharts of FIGS. 8 and 9 by developing and executing the printer driver update program stored in the ROM on the RAM.

  First, the printer driver update program determines whether there is a printer icon registered in association with the UPD 18 (S101). If there is no corresponding printer icon, the series of update processing ends. If there is a corresponding printer icon, the printer driver update program (information acquisition unit 19a) updates the update information of the new version of the UPD 18 to be installed from the predetermined file in the file group for installing the UPD 18 (S102). For example, the already installed UPD 18 is Ver. 1.0, and the UPD 18 to be installed is Ver.1.1. The update information of the UPD 18 of Ver.1.1 is as shown in FIG.

  Next, the printer driver update program (information acquisition unit 19a) acquires the upper limit value of the file size set in advance by the user (S103). The upper limit value of the file size is one that specifies the upper limit of the file size of all the UPDs 18 that are installed.

  Next, the printer driver update program (information acquisition unit 19a) acquires the usage status information of the corresponding printer icon from a file referred to by the old version UPD 18 (S104). This usage status information is as shown in FIG.

  Next, the printer driver update program (determination unit 19b) compares the update information acquired in S102 with the usage status information acquired in S104, and whether an update to the new version UPD 18 is required for each printer icon. It is determined whether or not (S105). Details of this determination processing will be described later.

  The processes of S104 and S105 are performed on all corresponding printer icons (S106), and then the printer driver update program (determination result display unit 19c) displays the determination result of the determination process of S105 on the display unit 14. (S107), and a series of update processing ends.

  FIG. 9 is a flowchart showing details of the determination process in S105. As an example, the update information in FIG. 6 and the usage status information in FIG. 7 will be used for explanation.

  First, the determination unit 19b sets an update unnecessary flag indicating whether or not an update to a new version of the UPD 18 is necessary to “No” (S201).

  Next, the determination unit 19b sequentially selects update information (S202), and determines whether the target model of the update information corresponds to the model of usage status information (S203). From FIG. 7, the model corresponding to the printer icon is Printer A. No. of FIG. For 1, since the target model is Printer E and is not applicable, the process skips to S210 and returns to S202 to select the next update information. No. No. 2, since the target model is Printer C and is not applicable, the process skips to S210 and returns to S202 to select the next update information. No. Since the target model is Printer A, which corresponds to 3, the process proceeds to S <b> 204.

  Next, the determination unit 19b determines from the update information whether the update type is model addition or function addition or failure handling (S204). No. of FIG. Since 3 corresponds to a defect, the process proceeds to S205.

  Next, the determination unit 19b determines whether or not the target function of the update information corresponds to the function of the usage status information (S205). No. of FIG. Reference numeral 3 is a countermeasure for a problem related to “staple”. In the usage status information of FIG. 7, the staple item is “available” and there is a corresponding function, so the process proceeds to S <b> 206. If there is no corresponding function due to differences in option configuration, etc., the process proceeds to S207.

  Next, the determination unit 19b determines whether there is a usage history for the corresponding function of the usage status information (S206). Since the item “staple” is “used” in FIG. 7, the process proceeds to S208, the update necessary flag is set to “Yes” (S208), and the process proceeds to the determination of the next update information (S210). If there is no usage history for the function, the process proceeds to S207.

  In the case of No in S205 or S206, the determination unit 19b sets the file size total value of the already installed UPD18 (Ver.1.0 UPD18) and the UPD18 (Ver.1.1 UPD18) to be installed in the future by the user. It is determined whether the file size is equal to or smaller than the upper limit of the file size (S207). If the total file size value is less than or equal to the upper limit value, the process proceeds to determination of the next update information (S210). If the total file size value exceeds the upper limit value, the update necessity flag is set to “Yes” (S208). The process proceeds to determination of the next update information (S210).

  Returning to S202, No. 5 in FIG. 4 update information is processed. No. Since the corresponding model 4 is Printer B and does not correspond to the model shown in FIG. 7 (No in S203), the process proceeds to the next update information (No in S210). Returning to S202 again, No. 5 in FIG. 5 update information is processed. No. 5 corresponds to the model in FIG. 7 (Yes in S203), but the “booklet” of the target function cannot be used in FIG. 7 (corresponding to the problem in S204, No in S205). move on. In addition, in FIG. Since the target model 6 is Printer D and does not correspond to the model of FIG. 7 (No in S203), the process proceeds to S210, and when all the update information processing is completed, the printer driver update program (update processing unit 19d) The updating process of the UPD 18 is executed under the conditions specified by default on the determination result display screen or the conditions specified by the user (S108). Details of the updating process of the UPD 18 will be described later.

  The above processing will be described by taking the case where the printer icon model is Printer C as an example. No. of update information in FIG. 2 and No. 5 target models are applicable (Yes in S203). No. Since the update information of 2 is a function addition, the process proceeds to S209, and the update necessary flag is set to “Yes”. No. No. 5 corresponds to the determination result of whether the booklet of the target function is in Printer C (S205) or if there is a function of the booklet (S206), because the update type corresponds to a defect. Process.

  Next, display of the determination result by the printer driver update program (determination result display unit 19c) in S107 of FIG. 8 will be described. When all the corresponding printer icons have been determined, the following three determination results are finally obtained.

(1) When all printer icons need to be updated In this case, the new version UPD 18 is installed, and the old version UPD 18 is deleted. A new version of UPD 18 may be overwritten and installed. Thereafter, all printer icons are updated in association with the new version of UPD 18. Specifically, the setting information in the usage status information is updated, or the display form of the printer icon is changed as necessary.

(2) When there are printer icons that need to be updated and printer icons that do not need to be updated In this case, the new version UPD 18 is additionally installed, and the old version UPD 18 is left without being deleted. As a result, the new version UPD 18 and the old version UPD 18 coexist. Thereafter, only the printer icon that needs to be updated is associated with the new version UPD 18 and updated.

(3) When all printer icons need not be updated In this case, the new version UPD 18 is not installed. All printer icons are used in a state of being associated with the old version UPD 18.

  FIG. 10 is a display example of the determination result display screen 41 when the determination result is (2). In the figure, the printer icon is represented as a printer. The determination result display unit 19c displays, in the update information column 41a, the printer icon name that is “update required = No” and the printer icon name that is “update required = Yes” in the determination process. The update method selection field 41b is an option for the update method of the UPD 18. Since the determination result is (2), the update method selection field 41b is in a state where “update only the printer that needs to be updated” is selected by default at the time of activation. When the user clicks the OK button 41d, the process specified in the update method selection field 41b is started, and when the user clicks the cancel button 41e, the update process is stopped.

  FIG. 11 is a display example of the determination result display screen 41 when the determination result is the above (3). The determination result display unit 19c displays in the update information column 41a that “update required = No” for all printer icons in the determination process. Since the determination result is (3), “not install” is selected by default in the update method selection column 41b at startup. When the determination result is (3), since there is no printer icon that needs to be updated, “update only the printer that needs to be updated” in the update method selection column 41b is preferably grayed out and cannot be selected.

  When the determination result is (1) above, the update method selection field 41b at startup is in a state where “update all printers” is selected by default.

  When the detailed information display instruction unit 41 c is clicked on the determination result display screen 41 of FIG. 10 or FIG. 11, the determination result display unit 19 c displays the determination result detail display screen on the display unit 14. FIG. 12 is a display example of the determination result detail display screen 42, which displays a list of determination results for all printer icons.

  The name column 42b is a printer icon name. The recommendation column 42c is a column for displaying the determination result. In the example of FIG. 12, “update recommended” is displayed when “update required = Yes”, and “unnecessary” is displayed when “update required = No”. But it ’s okay. The information column 42d displays the determination reason of the recommendation column 42c. The update column 42a is an item for selecting whether or not the user updates. At the start of the determination result display, the recommended column 42c is checked by default in the “update recommended” printer icon column, and the checked printer icon is updated.

  The size column 42e displays the already installed UPD 18 and the total file size value and upper limit value of the UPD 18 to be installed. The upper limit is displayed by default, but can also be entered by the user. When the total file size value after the installation becomes larger than the upper limit value, the printer icon displayed as “unnecessary” in the recommendation column 42c is changed to “recommended update” by the processing of S208 in FIG. When the OK button 42f is clicked, the printer icon checked in the update field 42a is updated, and when the cancel button 42g is clicked, the update process is stopped.

  As described above, since only the printer icon determined to be updated or the printer icon designated by the user is updated, only the updated printer icon needs to be checked, and the UPD 18 can be updated easily and appropriately. Can do.

  FIG. 13 is an example of printer icon usage status information different from FIG. If the determination is made by comparing with the update information in FIG. 6, the model in FIG. 5, no. No. 6, but no. “Booklet”, the target function of No. 5, cannot be used with Printer D. Since there is no usage history for “Punch” of the target function 6, all are “update required = No”, and the update is “unnecessary”. At this time, if the user does not check the update column 42a on the determination result detail display screen 42 in FIG. 12, the old version UPD 18 is used.

  However, in this case, no. The problem of 6 remains, and if the user uses the punch of the target function, a problem may occur. In order to prevent the occurrence of this problem, it is desirable to disable the corresponding function (gray out the punch setting field) on the print setting screen 40. If the user wants to use the corresponding function, it is preferable to notify the print setting screen 40 to update to a new version (display a message indicating that the function can be used by updating the version).

  FIG. 6 is an example of a print setting screen 40 when the user has not updated the UPD 18 even if there is an update of 6. The “Punch” function is grayed out and disabled according to the model / function restriction information set in the printer icon. If you click to use the punch, the specified information will be displayed according to the version information set in the printer icon. Notify you to update to a version. By performing such processing, it is possible to prevent a problem from occurring for a function that has not been updated because there is no usage history.

  Next, the update process in S108 of FIG. 8 will be described. The CPU executes the process of each step shown in the flowcharts of FIGS. 15 to 17 by expanding the printer driver update program stored in the ROM into the RAM and executing it. Note that the user instructs one of the following (a), (b), and (c) based on the determination result, and the printer driver update program (update processing unit 19d) performs processing according to the instruction.

(A) Update all printer icons (b) Update only some printer icons (some printer icons are not updated)
(C) Do not update all printer icons.

  FIG. 15 is a flowchart showing processing when all the printer icons are updated in the case of (a).

  First, the update processing unit 19d installs a new version of UPD 18 (S301). Next, the update processing unit 19d updates the printer icon (S302), and performs this update process for all the printer icons (S303). When all the printer icons have been updated (Yes in S303), the old version UPD 18 is uninstalled (S304).

  FIG. 16 is a flowchart showing processing when part of the printer icons is updated (there are printer icons that are not updated) in the case of (b) above.

  First, the update processing unit 19d installs a new version of UPD 18 (S401). Next, the update processing unit 19d checks whether or not the user has instructed to update the printer icon (S402). If “update” is instructed, the update processing unit 19d updates the printer icon (S403). On the other hand, when “not update” (uses the old version) is instructed, the update processing unit 19d determines whether there is a defect-compatible update in the new version UPD 18 (S404). Restriction information for defective models and functions is set in the icon (S405). At this time, version information of the new version UPD 18 is also set. The UPD 18 disables those models and functions on the print setting screen according to the restriction information set in the printer icon. Further, it is possible to notify the user to update to a new version according to the version information set in the printer icon. Then, the processes of S402 to S405 are performed for all printer icons (S406).

  FIG. 17 is a flowchart showing processing when not updating all printer icons in the case of (c). In the case of (c) above, the new version UPD 18 is not installed.

  First, the update processing unit 19d determines whether a new version of the UPD 18 has an update corresponding to a defect (S501). If there is a defect, the update processing unit 19d sets restriction information for the defective model and function in the printer icon ( S502). At this time, version information of the new version UPD 18 is also set. Then, the processes of S501 and S502 are performed on all printer icons (S503).

  As described above, the printer driver update program obtains and compares the update information of the new version UPD 18 and the usage status information of each printer icon, and needs to be updated to the new version UPD 18 for each printer icon. Since it is determined whether or not there is, and the determination result is displayed, unnecessary updates to the models and functions not used by the user can be suppressed, and the number of confirmation steps can be reduced. In addition, if the total file size of the UPD when the old version and the new version coexist is larger than a preset size, the update is recommended, so the burden on the computer apparatus due to the increase in the file size of the UPD is recommended. Can be reduced.

  In addition, this invention is not limited to the said Example, The structure and control can be changed suitably, unless it deviates from the meaning of this invention.

  For example, in the present embodiment, the case where the UPD 18 is installed in the client device 10 and the printer driver update program 19 is operated on the client device 10 has been described. However, the UPD 18 is installed in the server device 20 and the printer driver update program 19 is installed. The same applies to the case where the server device 20 is operated.

  In the above-described embodiment, the determination result display screen 41 displays the update information column 41a that describes whether or not each printer icon needs to be updated, and the update method selection column 41b that allows the UPD 18 update method to be selected. The update information column 41a and the update method selection column 41b may be displayed on separate screens.

  The present invention can be used for a printer driver update program that operates in an apparatus in which a printer driver is installed, a recording medium that records the printer driver update program, and a printer driver update method in the apparatus.
