Abstract
A printer apparatus that operates with power supplied by a power supply device includes: a printing unit that performs printing; a communication unit that is connected by USB to an external apparatus and supplies the power to the external apparatus; and a print control unit that causes the printing unit to perform printing in accordance with a print command received by the communication unit. When the printing unit performs the printing, the print control unit causes the communication unit to transmit a power-saving-enabling instruction that instructs the external apparatus to enter a power saving state.
