Abstract: A first and a second nozzle array eject a first and a second fluid, respectively. A control section controls the nozzle arrays while relatively shifting a relative position between the nozzle arrays and a medium. When printing normally, the relative position between the nozzle arrays and the medium is shifted towards one side by a transporting distance. When forming a second image using the second fluid over a first image formed using the first fluid, the second image's nozzles are located towards the one side relative to the first image's nozzles. When printing near an edge of the medium, a non-ejection one of the nozzles is located towards the one side of the first image's nozzles, and is located towards the other side of the second image's nozzles. A length of a region to which the non-ejection nozzle belongs is an integral multiple of the transporting distance.
