Abstract
A transport mechanism transports a medium in a transport direction based on a target transport amount and has a first roller provided on an upstream side in the transport direction and a second roller provided on a downstream side in the transport direction. Correction values are calculated based on an interval between the lines in the transport direction. The transport mechanism is controlled based on a corrected target transport amount after correcting the target transport amount based on the correction values. Lines are formed by ejecting ink from a first nozzle when the first roller is in contact with the medium, and ejecting ink from a second nozzle on a downstream side from the first nozzle in the transport direction when the first roller is not in contact with the medium and the second roller is in contact with the medium.
