A power on signal is automatically provided to turn on the printer power supply in accordance with a predetermined printing command, and a power off signal to turn off the printer power supply is automatically provided when the printer has not performed a printing operation for a predetermined time period. A low voltage and current switch is provided for manual on/off control of the printer power supply in accordance with an operation of a user.
