Abstract

An object of the present disclosure is to reduce power consumption while preventing a reduction in productivity. One embodiment of the present invention is a printing apparatus including: a print head that ejects a liquid; a circulation unit configured to circulate the liquid in a circulation path including the print head; a control unit configured to controls the circulation unit to execute periodic circulation by causing the circulation unit to circulate the liquid in the circulation path periodically at predetermined interval; and an input unit configured to input information on a suspension period during which the control unit suspends execution of the periodic circulation, wherein the control unit is set to start suspending the execution of the periodic circulation in accordance with the information and is set to resume execution of the periodic circulation when the suspension period indicated by the information is elapsed.

A printing apparatus comprising:

a print head comprising an ejection port to eject a liquid to a printing medium;
a circulation unit configured to circulate the liquid in a circulation path including the print head;
and
a control unit configured to control the circulation unit to execute periodic circulation by causing the circulation unit to circulate the liquid in the circulation path, and
wherein the control unit (1) performs execution of periodic circulation by causing the circulation unit to circulate the liquid in the circulation path for a first predetermined period and (2) in a case where a print job is executed in a second predetermined period from the end of the first predetermined period to resumption of the periodic circulation, performs execution of periodic circulation by causing the circulation unit to circulate the liquid in the circulation path for a third predetermined period which is shorter than the first predetermined period in response to execution of the print job.
