ABSTRACT:
A printer with a main body having a printing head, motors, a plurality of circuits driving the printing head and the motors, a processor and a random access memory. The printer also includes a cartridge for containing memory devices for storing the data for at least one character font set and for storing the printing operation control program. A connector removably connects the cartridge mechanically and electrically to the main body of the printer. As a result, the print operation control program and character font set data can be selectively set by connecting an appropriate cartridge to the main body of the printer.
