Abstract: A multifunctional printer is provided with a main CPU that controls the entire apparatus, main power unit that supplies power to the main CPU, sub CPU that shuts down the power supply from the main power unit to the main CPU at a predetermined condition and restores the power supply from the main power unit to the main CPU upon detecting a factor canceling the power supply shut-down, PC interface board that informs the sub CPU about the factor canceling the power supply shut-down upon detecting a printing request from a PC, and sub power unit that supplies the power to the sub CPU and PC interface board separately from the main power unit.
