ABSTRACT:
By suppressing deviation of dot-formation positions stemming from insufficient accuracy in conveying a printing medium due to eccentricity of a conveying roller, a printed image in which unevenness is less visible is obtained. An accumulated amount of conveyance errors is reduced by narrowing a nozzle-use range and by reducing a conveyance amount over an entire printing region according to the number of colors to be used and desired printing quality in printing an image. Moreover, the nozzles used when the nozzle-use range is narrowed are not fixed, and are switched to be used as appropriate. This prevents only certain nozzles from being used concentratedly, and allows all of the nozzles to maintain substantially the same ejection performance.
