  If the authentication function of the device of the own terminal is valid and the result of determination 402 is YES, it is checked whether account information exists without print data (determination 403). When the result of the determination 403 is NO, the network compatible multi-function peripheral FX acquires the address information of the personal computer devices PC1 to PCn used by the requesting user (process 404), and uses restriction information together with its own address information. By transmitting to the authentication server device SM having the database, the use restriction setting of the corresponding request source user is acquired from the authentication server device SM (process 405).

  The network compatible MFP FX checks whether or not the device use request at that time is a function permitted by the obtained use restriction setting (decision 406), and when the result of judgment 406 is YES, the requested function is displayed. If the result of determination 406 is NO, the requested function is not executed and an execution non-permission notice is issued to the requesting user (process 408).

  On the other hand, if the count information is incorporated in the print data and the result of determination 403 is YES, it is checked whether the account information in the print data is prioritized (determination 409). When the result of determination 409 is NO, the process proceeds to process 404 and the subsequent processes are executed.

  When the result of determination 409 is YES, the network-compatible MFP FX executes only the functions permitted by the guest use restriction setting, and if the functions are not permitted, the function is not performed and the request source is not executed. Issue a notice of execution disapproval to the user.

  If the authentication function of the device of the own terminal is invalid and the result of determination 402 is NO, the process proceeds to process 406 and the requested function is executed as it is.

  As described above, in each of the above-described embodiments, even when a function using a protocol that cannot add account information to print data is used, the use of the function can be restricted for each user. Further, by associating the address information of the personal computer device used by the user with the account information already registered in the authentication server device SM, it is possible to efficiently limit use. In addition, it becomes possible to specify the user of the device using the IP address and restrict the use of the function.
