The power control means generates a power control signal in a logic state for controlling the power supply means in response to a power off signal in a logic state applied from the control means and applies it to the power supply means. According to the logic state of the power control signal applied to the power supply means, the power supply means is shut down to cut off the power supplied to each part of the printer system. On the other hand, a power restore signal in a logic state is applied to the power control means by a switching operation of a key switch provided in a user interface, and the power control means generates a power control signal corresponding to the logic state of the power restore signal to generate the power. The operation of the supply means is resumed.
