Abstract:
A printing apparatus includes: a printhead configured to print an image by discharging ink to a first surface as a front surface of a printing sheet and a second surface as a back surface of the printing sheet; a conveyance roller configured to perform a first conveyance operation of conveying a printing sheet to a position facing the printhead, and a second conveyance operation of conveying the printing sheet in a direction opposite to a conveyance direction in the first conveyance operation after the image is printed on the first surface of the printing sheet; a reversing roller configured to reverse the printing sheet conveyed by the second conveyance operation; and a control unit configured to control a driving speed of the reversing roller based on an ink discharge amount on the first surface of the printing sheet.
