In a printing device, a print medium is transferred in a sub-scanning direction, a print head is reciprocately driven in a main scanning direction, a plurality of nozzles for ejecting same color ink in the sub-scanning direction are provided on the print head to form a nozzle array, pairs of nozzle arrays of a plurality of colors are arranged in the main scanning direction so as to be in a symmetrical sequence relative to the main scanning direction, and nozzle data for ejecting the ink at each nozzle in each nozzle array is created to perform printing. The printing device includes an inclination information acquisition part configured to obtain inclination information on an inclination of the nozzle array with respect to the sub-scanning direction, and a nozzle data allocation changing part configured to change the nozzle data to be allocated for each nozzle based on the inclination information.
