<P>PROBLEM TO BE SOLVED: To prevent a malicious user from intentionally copying a setup program to set up an optional function in a plurality of image forming apparatus as in the conventional practice by allowing an optional function for only one image forming apparatus to be set up even though the setup program is copied. <P>SOLUTION: When only one image forming apparatus ID stored in a PC 401 coincides with a self-machine ID stored in an image input-output system 100, an optional function of the image input-output system 100 is subjected to setup process in accordance with information about the validity/invalidity of the optional function of the image input-output system 100 instructed by the PC 401 side. If the apparatus ID does not coincide with the self-machine ID, control is performed so as not to perform the setup process of the optional function of the image input-output system 100, which corresponds to information instructed by the PC 401 side. <P>COPYRIGHT: (C)2004,JPO |
