A print data generating to generate print data to be used in a printing apparatus (1) which is capable of ejecting ink drops in a specific color on one spot to form a pixel, including, a plurality of inkjet heads (11,12,13,14), each of which has nozzles aligned in line, a usable nozzle number determining unit to determine a number of at least one usable nozzle to be used, a count storing unit to store a count of ejecting operations of each nozzle to be performed, a usable nozzle extracting unit to extract the at least one usable nozzle among the grouped nozzles, and a print data generating unit to generate the print data, which controls the at least one usable nozzle to eject the ink. The usable nozzle extracting unit extracts at least one nozzle with a lower count of ejecting operations preferentially to be the at least one usable nozzle.
