<P>PROBLEM TO BE SOLVED: To lock each of a plurality of setting items and allow a user to release the lock through an easy operation. <P>SOLUTION: A computer 15 executes a driver program 14 to achieve processing units 31-34. Based on lock setting data 22c, a setting change processing unit 33 determines whether to prohibit changing the value of each setting item. A display control unit 31 causes a lock release button to be displayed only on a tab screen containing setting items whose values are prohibited from being changed by the lock setting data. If authentication is successful when a user operates the lock release button, the display control unit 31 temporarily hides the unlocking button on all the tab screens. The setting change processing unit 33 temporarily permits to change the values of the setting items locked by the lock setting data 22c, without changing the lock setting data 22c. <P>COPYRIGHT: (C)2011,JPO&INPIT |
