Abstract:
An inkjet printer includes a transfer unit that transfers a paper, a print unit that has three or more nozzle rows aligned along a transfer direction of the paper, and a controller that ejects ink on the paper by controlling the print unit while transferring the paper by controlling the transfer unit. The most-upstream nozzle row of the nozzle row and the most-downstream nozzle row are capable of ejecting ink whose color has a lowest brightness among colors of ink to be used for printing. The controller selects the most-upstream nozzle row or the most-downstream nozzle row as a nozzle row for ejecting the ink whose color has a lowest brightness according to a type of the paper. According to the printer, it becomes possible to restrict contaminations on a printed media while also restricting degradation of print quality.
