Printing apparatus acquiring color correction data before entering a power saving mode

摘要

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.

主权项

1. A controlling apparatus for controlling an apparatus having a first power mode and a second power mode as an operation mode, the apparatus comprising:
a first controlling unit configured to control power supply so that power is supplied to a first circuit and a second circuit in the first power mode and so that power is not supplied to the first circuit and is supplied to the second circuit in the second power mode, wherein the first circuit includes a first storage unit for storing correction data and an execution unit for executing a process and wherein the second circuit includes a second storage unit, a receiving unit for receiving a request for acquiring the correction data, and a transmitting unit for transmitting the correction data to an external apparatus, and the second circuit is connected to the first circuit; and a second controlling unit configured to acquire the correction data from the first storage unit and store the acquired correction data in the second storage unit, prior to transition from the first power mode to the second power mode.
