Disclosed herein is a method of managing a printing apparatus including a thermal print head. The method of managing a printing apparatus includes: starting, by the controller of a printing apparatus, the cleaning of a thermal print head when a predetermined condition is satisfied; selecting, by the controller, a cleaning method based on at least one the satisfied condition and previously stored information; and cleaning, by the controller, the thermal print head by driving at least one of heating elements, included in a plurality of recording elements constituting the thermal print head, according to the selected cleaning method.

Method of managing thermal printer and thermal printer for performing the same

Provided is an image display device including: a communication unit configured to receive, from a control device, a control command for controlling an operation of the image display device; a memory storing one or more instructions; and a processor configured to execute the one or more instructions stored in the memory, wherein the processor is configured to execute the one or more instructions to: receive first user information about a first user corresponding to a user of the control device and authentication state information representing a user authentication state in the control device; when the control command includes an operation request that requires authentication, perform the authentication based on the first user information, the authentication state information, and second user information about a second user corresponding to a user of the image display device; and perform the operation in response to the control command.

Image display device and method for operating same

A printing apparatus supporting USB type-C includes: a USB type-C interface configured to support a connection with an external device; a printing unit configured to perform printing; and a controller configured to control the supply of power to the external device. The controller checks a reception power received from an external power source, predicts the 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.

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

A printer and a printing method are proposed. The printer and the printing method include transferring printing paper until a cutting target marker first disposed after a location at which the printing of a unit output has been completed based on the transfer direction of the printing paper reaches a cutting position, and cutting the corresponding location when the printing paper is transferred until the cutting target marker reaches the cutting position.
