Abstract
A printing apparatus includes: a printing section including a plurality of printing elements that performs printing on a medium; a power supply circuit supplying power to the printing section; a control circuit controlling the printing section and the power supply circuit; and a USB-Type-C interface configured to couple an external device and including a data transmission/reception terminal, a power input/output terminal, and a state identification terminal. When the state identification terminal detects that the external device that receives the power via the power input/output terminal is coupled, and the printing section performs printing, an amount of power supplied to the external device is large in a case in which a drive rate of the plurality of printing elements is low as compared with a case in which the drive rate of the plurality of printing elements is high.
