Abstract

A printing apparatus (101) includes: an ejection unit (110) configured to perform a print operation of forming an image on a print medium (103) by ejecting liquid from an ejection port by using drive of an ejection energy generation element (423) provided in a pressure chamber (424), the liquid flowing into the pressure chamber from a first flow passage (431); a sensor (S1-S9) configured to detect temperature of the ejection unit; a circulation unit (408) configured to circulate the liquid in a circulation flow passage including the first flow passage, the pressure chamber, and a second flow passage (432) configured to allow the liquid in the pressure chamber to flow to an outside of the pressure chamber; a recovery unit (210) configured to performs a cleaning operation of the ejection unit; and a control unit (301) configured to set wait time from completion of the print operation to execution of the cleaning operation depending on the temperature of the ejection unit detected by the sensor, and to execute the cleaning operation by the recovery unit in the case where elapsed time from the completion of the print operation exceeds the wait time.
