Title:
PRINTER
Document Type and Number:
Japanese Patent JP3181779
Kind Code:
B2
Abstract:
PURPOSE: To reduce a power-consumption at the time of non-printing in comparison with that of a prior art.
CONSTITUTION: A printer is divided into a controller part 110 and an engine part 120. In the controller part 110, a host interface IOP 111 receiving/ transmitting data from/to a RAM 116 is constantly supplied with a power and is in an operating state as long as a main switch of the device is in an ON state. In a power consumption reduction mode, i.e., in a sleep state in a non- printing state, the IOP 111 interrupts a power supply not only to the engine part 120 but also to circuits connected to a bus 118. If a predetermined command is received in a sleep state, a power supply thereto is started.
