Classification: CPC H  Y | IPC H

Claim 0:
1. A printer comprising:
a printing unit configured to be driven by a power supply from a battery which is charged by a charge IC, the printing unit including a printing mechanism that executes printing on a medium; and
a processor configured to:
set a mode of the printer to a print mode in which the printing unit executes printing; and
set the mode of the printer to a low-power mode in which total power consumption of the printer is lower than that in the print mode, in a state that the printing unit stops printing,

wherein in a case where the processor sets the mode to the low-power mode, the processor sets the mode to:
a first low-power mode as the low-power mode, in which the charge IC is driven at a first SW frequency, in a case where the charge IC works to charge the battery; and
a second low-power mode as the low-power mode, in which the charge IC is driven at a second SW frequency lower than the first SW frequency, in a case where the charge IC stops the charge of the battery,
wherein in the low-power mode, a controller configured to execute control of the printing unit is driven at a first clock frequency, and
wherein the first clock frequency in the second low-power mode is identical to the first clock frequency in the first low-power mode.
