Abstract
A control information storage unit writes control information for a printer (10) in a volatile RAM (16) during normal operation. When the power source is turned off, the control information stored in the RAM is transferred to an EEPROM (17) while the supply voltage is dropping. Thus, when the power source is turned off, the control information is maintained in the EEPROM in a stable state without the need for a backup power source. <IMAGE>
