PROBLEM TO BE SOLVED: To reduce nozzles prone to be an idle state as much as possible in an inkjet printer which can perform frameless printing of an image etc. to an entire region of a printing medium in a width direction. SOLUTION: The inkjet printer is equipped with the line type first heads 2, and the serial type second head 3 which can move back and forth along the width direction of a printing paper P. An arrangement length in the width direction of a plurality of first nozzles of the first head 2 is shorter than the width of the printing paper P. Also the plurality of first nozzles are arranged to be opposed to a width direction center part of the printing paper P. Liquid droplets of ink are jetted from the plurality of first nozzles of the first heads 2 to the first region A1 of the width direction center part of the printing paper P. Liquid droplets of ink are jetted from the second nozzles of the second head 3 to the second regions A2 located closer to both end sides in the width direction than the first region A1.
