摘要:
A printer has a backed-up memory unit for storing an optional emulation program. A CPU performs an installation of the optional emulation program contained in an emulation cartridge which is inserted in an expansion slot. The optional emulation program thus installed can be used to interpret control codes and print data relayed to the printer from a host computer.
