1. A printing device comprising: (A) a transporting section that transports a medium in a transporting direction; (B) an upstream side background color nozzle that ejects background color ink to the medium; (C) an upstream side color nozzle that ejects colored ink to the medium; (D) a downstream side background color nozzle that is provided further in the downstream side of the upstream side background color nozzle row in the transporting direction, and ejects the background color ink to the medium; (E) a downstream side color nozzle that is provided further in the downstream side of the upstream side color nozzle in the transporting direction, and ejects the color ink to the medium; (F) a moving section that moves the upstream side background color nozzle, the upstream side color nozzle, the downstream side background color nozzle, and the downstream side color nozzle, in intersecting directions that intersect the transporting direction; and (G) a controlling section that makes the upstream side background color nozzle and the upstream side color nozzle form a background image by moving the upstream side background color nozzle and the upstream side color nozzle in the intersecting directions, and makes at least the downstream color nozzle form a color image, by moving the downstream color nozzle in the intersecting directions, wherein the upstream side background color nozzle and the upstream side color nozzle are made to eject the respective inks thereof to tone the background image, when the background image is formed; wherein an area where image is formed by the upstream side background color nozzle and an area where image is formed by the upstream side color nozzle overlap partially at least.
