Abstract
A printing apparatus includes a suction unit configured to suction liquid from an ejection port, a valve provided at a first position in a supply passage and configured to be switchable between an open state in which the supply passage communicates and a closed state in which the supply passage is blocked, and a control unit configured to perform control of first suction in which the valve is set to the open state and the suction unit performs the suction, such that the liquid reaches the first position or a second position downstream of the first position, after the first suction, to perform control of second suction in which the valve is set to the closed state and the suction unit performs the suction, and, after the second suction, to perform control of setting the valve to the open state.
