Power control method of printing apparatus

A control method of a printing apparatus including:

• a printing mechanism configured to form an image on a printing medium;
• a printing controller configured to control the printing mechanism and to store data relating to the printing mechanism;
• a power controller configured to supply power to the printing mechanism and the printing controller, and to stop the supply of power to the printing mechanism and the printing controller;
• and
• a main controller connected with the printing controller so as to be capable of communication, the control method comprising:
• a step of, by the main controller, transmitting each of a data acquisition request and an end request to the printing controller in accordance with a predetermined condition;
• a step of, by the power controller, stopping the supply of power to the printing mechanism in accordance with a predetermined response for the data acquisition request;
• a step of, by the main controller, acquiring the data relating to the printing mechanism stored by the printing controller in accordance with the predetermined response for the data acquisition request;
• and
• a step of, by the power controller, stopping the supply of power to the printing controller after a completion of acquisition of the data relating to the printing mechanism stored by the printing controller.

• a printing controller configured to control the printing mechanism and to store data relating to the printing mechanism;
• a power controller configured to supply power to the printing mechanism and the printing controller, and to stop supplying power to the printing mechanism and the printing controller;
• and
• a main controller connected with the printing controller so as to be capable of communication, wherein
• the main controller acquires the data relating to the printing mechanism stored by the printing controller in accordance with a predetermined condition, and
• the power controller stops supplying power to the printing mechanism without waiting for a completion of acquisition of the data relating to the printing mechanism stored by the printing controller.
