Abstract
A printing apparatus receives information indicating a type of printing medium from an information processing apparatus, and determines whether data for performing color correction corresponding to the type of printing medium indicated by the information is stored. If it is determined that the data is stored, the printing apparatus transmits the data from a sub-board to the information processing apparatus, receives image data to undergo color correction from the information processing apparatus, and prints an image based on the image data on a main board. The printing apparatus shifts to the power saving mode by restricting power supply to the main board, and returns from the power saving mode upon receiving image data to undergo color correction from the information processing apparatus.
Claims5
A printing apparatus which operates in a normal power mode and a power saving mode, comprising:
- a power supply unit;
- a first control unit configured to include a communication unit for communicating with an external apparatus and receive power supply from said power supply unit in the normal power mode and the power saving mode;
- and
- a second control unit configured to include an acquisition unit for acquiring color correction data and a transfer unit for transferring, to said first control unit, color correction data corresponding to a type of printing medium set in the printing apparatus before stopping power supply from said power supply unit in order to shift the printing apparatus from the normal power mode to the power saving mode.
