Abstract
A printing device includes: a print head having nozzles for printing different size dots; an acquirer acquiring discharge deviation characteristic information of the nozzles; an acquirer acquiring M-level image data (M≧3); an identifier identifying pixels relating to discharge deviation based on the discharge deviation characteristic information from the discharge deviation characteristic information acquirer out of respective pixels in the M-level image data; an adjuster adjusting pixel values of the pixels relating to the discharge deviation from the deviated pixel identifier; a generator generating N-level data (M>N≧2) for image data in which the pixel value is adjusted; a generator generating the print data to which the dots having sizes corresponding to the respective pixels are allocated based on the N-level data, and a printer using the print head to print based on the print data.
