A printing apparatus includes a printing head that has a plurality of nozzle modules corresponding to various ink colors arranged in parallel, an abnormal nozzle specifying unit that specifies an abnormal nozzle that is deviated from an ideal dot printing position by a predetermined distance or more among nozzles constituting each of the nozzle modules of the printing head, and a density correction unit that corrects a density of a dot printing line to be printed by the nozzles including the abnormal nozzle specified by the abnormal nozzle specifying unit and printing the same line as the abnormal nozzle. The density correction unit corrects printing data corresponding to the dot printing line printed by the nozzles including the abnormal nozzle and printing the same line as the abnormal nozzle so as to be close to densities of other dot printing lines to be printed by only normal nozzles.
BACKGROUND
[0002] 1. Technical Field
[0003] The present invention relates to a printing apparatus used in a facsimile machine, a copy machine, a printing apparatus for an OA instrument, or the like, to a printing apparatus control program, and to a printing apparatus control method. In particular, the present invention relates to a printing apparatus that is suitable for performing so-called ink jet printing by ejecting fine particles of liquid ink of a plurality of colors on a printing paper (that is, a recording medium) and rendering a predetermined character or image, to a printing program, to a printing method, and to a recording medium having recorded thereon the program.
SUMMARY
[0018] An advantage of some aspects of the invention is that it provides a printing apparatus that can easily remove a banding phenomenon due to a deviation in printing position occurring particularly in a printing direction or make the phenomenon almost unnoticeable, a printing program, a printing method, a printing control device, a printing control program, a printing control method, and a recording medium having recorded thereon the program.
