Patent ID: 8374522

Claim:
A printing apparatus comprising: a printing unit configured to perform print processing on a sheet based on image data; a selection unit configured to select between a first print mode and a second print mode, the first print mode being for conveying a sheet at a first speed and performing monochromatic print processing for all pages, and the second print mode being for conveying a sheet at a second speed lower than the first speed regardless of whether each page included in the image data is monochromatic image data or color image data and performing monochromatic print processing for a page of the monochromatic image data and performing color print processing for a page of the color image data; a control unit configured to control the printing unit to perform print processing in the print mode selected by the selection unit; and a performance unit configured to perform a first shifting process which is for shifting the printing unit to a state that the monochromatic print processing can be performed and a second shifting process which is for shifting the printing unit to a state that the color print processing can be performed, wherein in a case where the selection unit selects the first print mode, the performance unit performs the first shifting process to start the print processing, and wherein in a case where the selection unit selects the second print mode, the performance unit performs the first shifting process to start the print processing and further performs the second shifting process when a page of color image data is printed.
