ABSTRACT:
A printing machine (1) and a printing system (A) are disclosed as having a ROM (5) which stores, in addition to a program for realizing a specific function available for service, all programs for realizing specific functions rendered non-available for service, with service permit information representative of service permit/prohibition of these specific functions being stored in a service permit information storing unit (7). A display and input device (4) provides a display of only the specific function rendered available for service in service permit information stored in the service permit information storing unit (7) whereby, when a particular specific function displayed over the display and input device (4), the program interrelated with the selected specific function is retrieved from the ROM (5) to be executed for operation to realize the selected specific function.
