A printing apparatus prints by discharging inks from respective nozzle arrays, the printhead having a plurality of nozzle arrays including at least a first nozzle array, a second nozzle array, and a third nozzle array, and the first nozzle array and the second nozzle array being arrayed to be shifted in a nozzle arrayed direction. The printing apparatus controls the first and second nozzle arrays to discharge inks to form a plurality of first patterns. The printing apparatus controls the third nozzle array to discharge inks to form second patterns while changing a shift amount in a direction which intersects with the nozzle arrayed direction with respect to the plurality of first patterns. The printing apparatus calculates an adjustment value required to adjust relative printing positions between the first nozzle array and the third nozzle array in the intersecting direction using the first patterns and the second patterns.
