Abstract
A printing apparatus includes a mounting unit, a tank, a pump, a detection unit, an obtainment unit, and a control unit. The mounting unit is configured so that a head that ejects ink can be mounted in a replaceable manner. The tank contains ink to be supplied to the head via a tube. The pump discharges ink to an outside of the head. The detection unit detects that the head mounted on the mounting unit has been replaced. The obtainment unit obtains information of a usage history which indicates whether or not the head mounted as a replacement has been used. The control unit controls a discharge operation, which is performed by the pump after head replacement, to be changed based on the information of the usage history.
