Abstract
An ink jet printing apparatus performs printing on a print medium, and includes a print head having a plurality of ejection openings, a head temperature acquisition unit that acquires a temperature of the print head, and a heating unit configured to heat the print head. In addition, a control unit is configured to control the heating unit so as to cause a temperature of the print head to be a target temperature, at start of a print scan by the print head, and a setting unit is configured to set the target temperature. If a completion temperature acquired by the acquisition unit at a time when a previous print scan is completed is lower than a threshold temperature, the setting unit sets a temperature higher than the completion temperature as the target temperature, and if the completion temperature is equal to or higher than the threshold temperature, the setting unit sets a temperature lower than the completion temperature as the target temperature.
