1. A printing apparatus comprising:
a tank configured to store liquid to be supplied to a print head which ejects the liquid to a print medium to perform printing;
a first path configured to connect the tank and the print head;
a second path configured to connect the tank and the print head;
a third path branching from the first path;
a valve provided in the third path and configured to open the third path and to close the third path, wherein in a case where the print head performs printing, the valve is closed;
a pump configured to flow the liquid so that the liquid flows from the first path to the print head and from the print head to the second path; and
a control unit configured to perform first control so that a flow rate of the liquid caused to flow in the second path by the pump is a first target flow rate and to perform second control so that a flow rate of the liquid caused to flow in the second path by the pump is a second target flow rate greater than the first target flow rate.
