Method for supplying power using printing apparatus, and printing apparatus for performing the same

A printing apparatus supporting USB type-C, the printing apparatus comprising:

• a USB type-C interface configured to support a connection with an external device;
• a printing performer configured to perform printing;
• and
• a controller configured to control supply of power to the external device;
• wherein the controller checks a reception power received from an external power source, predicts an estimated power consumption of at least one of the printing apparatus and the external device, determines a supply power to be transmitted to the external device based on the reception power and the estimated power consumption, and transmits the supply power to the external device via the USB type-C interface,
• wherein the controller determines the supply power based on at least one of a minimum amount of power required by the printing apparatus and priorities of the printing apparatus and the external device, the reception power, and the estimated power consumption.
