    摘要: The printing apparatus includes a control-section for forming an image on a print-medium by repeating an image-formation-operation and a transport-operation. Through the image-formation-operation, a plurality of nozzle-arrays discharges an ink while a moving-mechanism moves the plurality of nozzle-arrays, and through the transport-operation, the print-medium is transported to the transport-mechanism. The control-section forms a first-image by using a nozzle group for the first-image. The nozzle-group for the first-image is formed of N nozzles included in a first-nozzle-array of the plurality of nozzle-arrays. In addition, the control-section forms a second-image, which overlaps with the first-image on the print-medium, by using a nozzle-group for the second-image. The nozzle-group for the second-image is formed of M nozzles among the nozzles included in the second-nozzle-array of the plurality of nozzle-arrays, and the position of the nozzle-group for the second-image is different from that of the nozzle-group for the first-image in a first-direction.
