An ink jet printer with a transportation device which transports a print medium along a first direction, first and second ink jet heads, and a head moving device. The first ink jet head has a first nozzle line with a plurality of nozzles aligned along a direction intersecting with the first direction. The second ink jet head has a second nozzle line with a plurality of nozzles aligned along a direction intersecting with the first direction. The head moving device moves the first ink jet head with respect to the second ink jet head along a direction intersecting with the first direction, between a first positional relationship, where the first and second nozzle lines overlap each other along a second direction perpendicular to the first direction, and a second positional relationship, where the first nozzle line and the second nozzle line do not overlap each other along the second direction.
