Abstract
A printing apparatus includes a printing section performing printing, and a USB-Type-C interface configured to perform switching to a first state in which a printing operation is executed or a second state in which the power is supplied to the external device. The USB-Type-C interface includes a state identification terminal held at a first potential indicating that the USB-Type-C interface is coupled in the first state or a second potential indicating that the USB-Type-C interface is coupled in the second state. The state identification terminal is periodically switched between the first potential and the second potential during a unit time when the external device is not coupled to the USB-Type-C interface, and in the unit time, a time at which the state identification terminal is held at the second potential is longer than a time at which the state identification terminal is held at the first potential.
