Printing device and printing method

A printing device comprising:

• a print head that includes a plurality of nozzles configured to eject ink droplets onto a medium, and that includes a plurality of nozzle arrays in which the nozzles are arranged in a nozzle array direction and
• a control section configured to control ejection of the ink droplets from the nozzles, wherein
• the print head and the medium relatively move in a relative movement direction different from the nozzle array direction,
• the print head includes first nozzle arrays and second nozzle arrays that eject different ink droplets,
• a number of the first nozzle arrays and a number of the second nozzle arrays are each two or more,
• the plurality of nozzle arrays which eject ink droplets on a same line along the relative movement direction include a first nozzle region in which a distance between the first nozzle array and the second nozzle array in the relative movement direction is a first distance and a second nozzle region in which a distance between the first nozzle array and the second nozzle array in the relative movement direction is a second distance which is longer than the first distance,
• the nozzles are configured to form dots of a plurality of sizes on the medium by ejecting ink droplets of a plurality of sizes, and
• when a ratio of sizes of a plurality of ink droplets ejected from the nozzles of the first nozzle region is defined as a first ratio and a ratio of sizes of a plurality of ink droplets ejected from the nozzles of the second nozzle region is defined as a second ratio, the control section executes a first print in which a ratio of ink droplets having a size other than a maximum size in the second ratio is smaller than a ratio of ink droplets having a size other than a maximum size in the first ratio.
