Abstract
A printer includes a print head having nozzles forming dots on a medium; a unit acquiring image data having pixel values with M gray scales (M≧2); a unit storing nozzle characteristic information; a unit specifying a banding generating nozzle based on the nozzle characteristic information; a processor performing a banding prevention process for data corresponding to a banding generation line formed by the banding generating nozzle and a different line formed by a different nozzle near the banding generating nozzle; a controller controlling the banding prevention processor so that a process range includes the banding generation line and the different line, a density difference of a line adjacent to the different line falling within a predetermined numerical range; and a unit printing an image on the medium with the print head based on the image data subjected to the banding prevention process.
