Abstract
Efficient power conservation is enabled using a configuration having multiple processors. A printing device has a first processor unit that runs a program stored in a first memory, and a second processor unit that runs a program stored in a second memory, and has operating modes including a normal mode in which the first processor unit and the second processor unit operate according to a normal clock, and a first power conservation mode in which, after going to a state enabling the first processor unit to execute some processes of the second processor unit, the first processor unit operates according to the normal clock, and the second processor operates according to a slow clock having an operating frequency lower than the normal clock.
