Printing apparatus

A printing apparatus comprising:

• a printing unit configured with a nozzle array, in which a plurality of nozzles that eject ink to a print medium are aligned, and configured to move relative to the print medium in a direction intersecting a direction in which the nozzles are aligned;
• a detection unit configured to detect a temperature of the printing unit;
• and
• a determination unit configured to determine a driving pulse for ejecting ink, based on the temperature of the printing unit,
• wherein the determination unit is configured such that where first printing in which printing is performed by use of a first group, which includes nozzles of the nozzle array whose distances to the detection unit are less than a first predetermined value, is executed, and thereafter second printing in which printing is performed by use of a second group, which includes nozzles of the nozzle array whose distances to the detection unit are equal to or less than the first predetermined value and are equal to or more than a second predetermined value, is executed, the determination unit
• (1) determines a first driving pulse for the first printing by use of a first temperature, which is detected by the detection unit before the first printing is performed, and
• (2) determines a second driving pulse for the second printing (a) by use of a second temperature detected before the first printing and (b) without use of a temperature detected by the detection unit after the first printing.
