A control unit controls a print head to print a print image by ejecting ink through a nozzle to form dots on a print medium and a movement unit to impart relative movement between the print head and the print medium to print a print image on the print medium. The control unit obtains a dot adjustment value in the predetermined print operation based on the measurement result of a measurement unit measuring a first pattern composed of a print image printed by the predetermined print operation including the relative movement, and a second adjustment value for adjusting dot printing positions in the predetermined print operation in a unit of length shorter than in the adjustment using the first adjustment value based on a second pattern printed by the predetermined print operation in a density according to density information on the first pattern, measured by the measurement unit.
