Abstract
In an inkjet printer, a first sparsely arranged portion of a first ejection head entirely overlaps in a movement direction with a second densely arranged portion of a second ejection head. A plurality of outlets of the first sparsely arranged portion include use outlets, and among a plurality of outlets of the second densely arranged portion, those that overlap in the movement direction with use outlets of the first sparsely arranged portion are non-use outlets. In an overlapping range of the first ejection head and the second ejection head, outlets of both of the ejection heads are used in recording an image onto a base material. Consequently, it is possible to prevent or suppress a reduction in print quality such as changes in density or the occurrence of voids due to displacement of the mounting positions of ejection heads in the overlapping range.
