Abstract
A printing apparatus includes an ejection unit that forms an image on a print medium by ejecting liquid from an ejection port using drive of an ejection energy generation element in a pressure chamber, the liquid flowing into the pressure chamber from a first flow passage, a circulation unit circulates the liquid in a circulation flow passage including the first flow passage, the pressure chamber, and a second flow passage to allow the liquid to flow to outside of the pressure chamber, a recovery unit performs a recovery operation of the ejection unit, and a control unit stops the circulation unit before completion of the print operation when the recovery operation is to be performed after the print operation, such that a flow velocity at a timing of the completion of the print operation is a flow velocity higher than a flow velocity at which an ejection characteristic is maintained.
