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.

摘要:
A printing apparatus includes a controller forming an image on a printing-medium by repeating an image-forming-operation of allowing a plurality of nozzle-columns to be moved and allowing the plurality of nozzle-columns to eject ink and a transporting-operations of allowing the printing-medium to be transported. The controller forms a first-image by an image-forming-operation where the moving-direction of a nozzle-column is one direction in a second direction by using a first-image-nozzle-group configured with the nozzles included in the first-nozzle-column. In addition, the controller forms a second-image which is overlapped with the first-image by an image-forming-operation where the moving-direction of a nozzle-column is one direction and by an image-forming-operation where the moving-direction of the nozzle-column is the direction opposite to the one direction by using a second-image-nozzle-group configured with the nozzles of which positions in the first direction are different from those of the first-image-nozzle-group among the nozzles included in the second-nozzle-column.
