Abstract
A printer comprises an ink-jet head, and a control unit which has a judgment pattern printing control section. When a judgment pattern is printed, the judgment pattern printing control section allows the discharge of ink droplets of a second color to an area on which ink droplets of a first color are to be landed, before discharging the ink droplets of the first color having a small color difference with respect to a color of a medium. Accordingly, the ink discharge malfunction is reliably judged for the nozzle irrelevant to the color of the recording medium and the color of the ink discharged from the ink-jet head.
