Abstract: To provide a printing apparatus and a method for determining a service life of a cleaning mechanism, capable of more accurately determining a service life of a cleaning mechanism. For the purpose, a service life of a recovery unit is determined by multiplication of a number of times a blade wipes a face surface by a coefficient different depending on a quantity of liquid adhering to the face surface.

Abstract: The present invention intends to provide a printing apparatus that can lessen a reduction in ejection performance caused by thickening, solidification, or the like of print liquid in an ejection port of a printing unit even in the case of stopping a print operation by the printing unit to perform a post-process on a print medium. The printing apparatus includes a post-processing part configured to, in a state of stopping the print operation by the printing unit, perform the post-process on a printed print medium as well as including an open/close unit configured to selectively perform a closing operation or an opening operation of the ejection port provided in the printing unit. Further, when the print medium is stopped in the post-processing part, the open/close unit is controlled so as to bring the ejection port into a close state.
