Abstract
There is disclosed an information processing apparatus, such as a printer, capable of selectively using plural control programs by utilizing an external memory, such as a program cartridge, containing additional programs. When a switching of control program is requested for example by a switch, the start address of the requested program is indirectly obtained by referring to a fixed address of the memory cartridge containing the requested program.
