ABSTRACT:
Control parameters necessary for controlling mechanism sections of a printing apparatus are stored in a program ROM. Selection data used for selecting predetermined control parameters stored in the program ROM are stored in a non-volatile memory. When operations of the mechanism sections of the printing apparatus are selectively changed, the selection data stored in the non-volatile memory are changed in accordance with operating states of the mechanism sections. The mechanism sections of the printing apparatus can be controlled upon every change in their operations without replacement of the ROM for storing the control parameters.
