Abstract: A print head has a first nozzle group that includes a plurality of first nozzles capable of ejecting a first liquid onto a medium, and a second nozzle group that includes a plurality of second nozzles ejecting a second liquid that is more visible than the first liquid onto the medium. A detection section is capable of detecting a first defective nozzle, which is ejection failure, from the first nozzle group without printing a test pattern indicating ejection state of each of the first nozzles on the medium. A control section causes a second nozzle test pattern indicating ejection state of each of the second nozzles to be printed on the medium using the second liquid, and information regarding the first defective nozzles detected by the detection section to be printed on the medium using the second liquid.
