On a printed board (550) of a cartridge (503) are arranged a microprocessor (601), a ROM storing a processing program for the microprocessor (601), and a ROM storing a processing program for a processor in a printer body. When the cartridge (503) is inserted in the printer body, the processor in the printer body reads discrimination data stored in the ROM in the cartridge, and the processor in the printer body performs the processing according to the predetermined processing program in response to the discrimination data. The microprocessor (601) is arranged at the forward end in the cartridge when inserted so that it is effectively cooled by the stream of the cooling air. |
