In the case of an electronic equipment mounted with an additional control device, by providing a means for storing the various preset values of the electronic equipment in the additional control device, the preset values can be changed easily each time the additional control device is connected or disconnected. The condition of a laser printer (1) communicating a workstation (7) and the preset number of printed copies, etc., are usually stored in an EEPROM (513) in the laser printer (1). When mounting the additional control device, i.e., a cartridge (3), a microprocessor (601) of the cartridge (3) stores the preset values of the laser printer (1) in an EEPROM (670). Therefore, the preset values of the EEPROM (513) are retained, and even when the cartridge (3) is dismounted, the laser printer (1) can operate immediately under the condition set in the EEPROM (513). |
