Printing apparatus, control method therefor, and nonvolatile computer-readable storage medium

A printing apparatus comprising:

• a printhead configured to execute printing by discharging ink from a discharge surface;
• a cleaning portion configured to clean the discharge surface;
• and
• a control portion,
• wherein the control portion includes
• a determination unit configured to determine, for every predetermined time during execution of the printing by the printhead, for each of a plurality of regions divided in one direction on the discharge surface, whether the number of times of ink discharge within the predetermined time exceeds a first threshold,
• a count unit configured to count, for each of the plurality of divided regions, the number of times the number of times of ink discharge within the predetermined time exceeds the first threshold, and
• an execution unit configured to, in a case where a count value of the count unit reaches a second threshold with respect to any of the plurality of divided regions, interrupt the printing by the printhead and cause the cleaning portion to execute the cleaning.
