RPCS ”, the operating OS is“ Win2000 ”, and the version is“ 1.0 ”indicates that the certified software is used. Note that the example shown in FIG. 6A indicates that the software corresponding to either the first row or the second row is certified software.

  In the example shown in FIG. 6B, the software ID matches one of “123456” (first line), “Aabbcc” (second line), and “xxyyzz” (third line). It shows that what is to be certified software.

  In the example shown in FIG. 6C, the software IDs are “123456” (first line), “Aabbcc” (second line), “xxyyzz” (third line), and “65536” ( It is shown that the one that matches any of the fourth line) is certified software.

  For example, if the software determination unit 122 receives the software authentication information shown in FIG. 5A and the certified software information shown in FIG. 6A, in this case, the driver name included in the software authentication information is Since it is “ABC RPCS”, the driver OS satisfies the condition indicated by the certified software information on the first line, and the operating OS and version included in the software authentication information are “Win2000” and “1.4.0.0” (ie, 1.2 or more), therefore, the conditions indicated by the certified software information on the first line are also satisfied for the incidental conditions. Therefore, in this case, the software determination unit 122 determines that the determination target printer driver is authorized software, and notifies the printing unit 124 of the determination result.

  On the other hand, when the software determination unit 122 receives the software authentication information illustrated in FIG. 5A and the certified software information illustrated in FIG. 6B, the software authentication information does not include the software ID. Therefore, none of the conditions included in the authorized software information is satisfied. Therefore, in this case, the software determination unit 122 determines that the determination target printer driver is not certified software, and notifies the determination result to the printing unit 124.

  The print unit 124 forms an output image based on the print data sent from the computer 110 and outputs it to a sheet. However, if the determination result notified from the software determination unit 122 indicates that the print data has not been generated by the authorized software (that is, the printer driver authorized to use), the printing unit 124 may No message is output, and a message notifying the user that printing has been stopped because the authorized software is not used is printed.

Upon receiving the notification, the printing unit 124 outputs an alert when the determination result indicates that the printer driver is not authorized software (S807). On the other hand, in the case of certified software, normal output processing is performed based on the received print data.

  Since the printing system 100 performs the processing as described above, if the certified software is not used, only an alert is output and the document cannot be printed. As a result, users are expected to install only printer drivers that the administrator has approved to use so that the intended print results can be obtained. Installation can be suppressed.

  In the embodiment shown in FIG. 8, the user confirms that the alert is output without actually printing the document or the like as a result of actually instructing the printing of the document or the like, and the software being used is Although it is recognized that the software is not certified, in the present embodiment, it is possible to confirm whether or not the software being used is certified software before printing. Next, an embodiment of processing in this case will be described.

  FIG. 9 shows an embodiment of a processing sequence in the printing system 100 in the case where it is confirmed whether the software being used is authorized software before printing.

The confirmation data includes printer driver software information. In the image forming apparatus 120, when the confirmation data is received, the software information detection unit 121 analyzes the confirmation data, detects the software information, and extracts the software authentication information.

  Then, the software information detection unit 121 sends the extracted software authentication information to the software determination unit 122 and requests to determine whether or not the printer driver is certified software (S902). Upon receiving the determination request, the software determination unit 122 makes an inquiry to the authorized software information management unit 123 to acquire authorized software information (S903). Upon receiving the inquiry, the authorized software information management unit 123 takes out the authorized software information managed by itself and passes it to the software determination unit 122 (S904). The software determination unit 122 that has received the authorized software information from the authorized software information management unit 123 compares the authorized software information with the software authentication information received from the software information detection unit 121, and the printer driver is authorized software. It is determined whether or not.

  Thereafter, the determination result is notified to the printer driver unit 112 via the network 130 (S905). Upon receiving the notification, the printer driver unit 112 performs screen display according to the content of the notification (S906).

  FIG. 10 is a diagram illustrating an example of a screen displayed on the display device of the computer 110 by the printer driver unit 112. FIG. 10A shows an example of a screen displayed when the confirmed printer driver is certified software, and FIG. 10B shows that the confirmed printer driver is not certified software. An example of a screen displayed in the case of an error is shown.

  In the screen shown in FIG. 10A, a message is displayed indicating that the printer driver that has confirmed is software that is permitted to be used in the image forming apparatus 120.

  On the other hand, on the screen shown in FIG. 10B, a message indicating that unauthorized software has been used and information on how to obtain available authorized software are displayed. Further, a hyperlink to the installation server is set in the information part about the method of obtaining the certified software (that is, the “here” part underlined). In this way, by displaying a hyperlink to the installation server on the screen that is displayed when the certified software is not being used, it is easy to install the appropriate printer driver, and the installation of the certified software is facilitated. It will be promoted more.

  Next, an embodiment of a method for registering / updating authorized software information in the printing system 100 will be described. In the printing system 100, it is assumed that the printer driver used when the administrator performs printing is the authorized software approved by the administrator, and the printer driver is not registered in the image forming apparatus 120 as the authorized software. Registers the printer driver in the image forming apparatus 120 as authorized software.

  FIG. 11 is an embodiment of a processing sequence in the printing system 100 when registering authorized software information.

  As shown in FIG. 10, in the computer 110, when the application unit 111 requests printing of a document (S1101), the printer driver unit 112 generates print data based on the document data and sends it to the image forming apparatus 120 (see FIG. 10). S1102). At this time, the printer driver unit 112 includes the software information of the printer driver used for generating the print data in the print data. However, in particular, when the user who issued the print instruction has the authority of administrator, the print driver The title information (for example, UserName = “Administrator” in FIG. 3C) indicating that the instructing user has the administrator title is included as software information.

  In the image forming apparatus 120, when print data is received from the printer driver unit 112, first, the software information detection unit 121 analyzes the print data, detects software information, and extracts software authentication information. At this time, when detecting the title information, the software information detection unit 121 determines that the printing is printing in the management mode, and registers the printer driver used for generating the printing data as authorized software. The extracted software authentication information is sent to the software determination unit 122 to make a registration request (S1103).

  Upon receiving the registration request from the software information detection unit 121, the software determination unit 122 requests the authorized software information management unit 123 to send authorized software information (S1104). The authorized software information management unit 123 that has received the authorized software information acquisition request from the software judging unit 122 obtains authorized software information from the authorized software information list 600 managed by itself, and sends it to the software judging unit 122 (S1105).

  The software determination unit 122 that has received the authorized software information from the authorized software information management unit 123 compares the software authentication information passed from the software information detection unit 121 with respect to whether or not the printer driver has been registered as authorized software. Determine. If the result of the determination is that the printer driver has not been registered, the software authentication information of the printer driver is sent to the authorized software information management unit 123 to request registration of the printer driver as authorized software (S1106).

  For example, if the software authentication information shown in FIG. 5C is passed from the software information detection unit 121 and the certified software information shown in FIG. 6B is received from the certified software information management unit 123, the software determination unit 122 Since the software ID as the software authentication information does not match the condition indicated by the certified software information (the value “65536” is not included as the software ID), it is determined that the software authentication information is not registered, and the software authentication information Is sent to the authorized software information management unit 123 to request registration as authorized software information. In this case, the content to be registered is the software ID “65536”. Upon receiving the registration request, the authorized software information management unit 123 updates the authorized software information as shown in FIG.

  When the registration of the authorized software information is completed as described above, the software determination unit 122 notifies the determination result to the printing unit 124 (S1107). Upon receiving the notification, if the determination result indicates that the printer driver is not registered as authorized software, the printing unit 124 outputs an alert to notify that the authorized software information has been registered (S1108).
