Abstract: Included are a transport unit, a printing unit, and a control unit. In inner circumferential surface printing for performing printing on an inner circumferential surface of a medium, which is positioned inside in the state of being wound up in a roll shape, the control unit causes the transport unit to position a leading end of the medium at a printing start position being a position downstream of a position facing a most downstream nozzle of a nozzle surface in a transport direction, in a state in which the printing unit is at a position at which the nozzle surface does not face the medium being transported by the transport unit, and causes the printing unit to start formation of a printing region on the medium having the leading end positioned at the printing start position.

Abstract: Included are a printing unit configured to perform printing on a medium (P) being transported, a first nipping roller configured to nip the medium at a first nipping position downstream of the printing unit in a transport direction in which the medium is transported, a second nipping roller configured to nip the medium at a second nipping position upstream of the printing unit, and a control unit. During duplex printing for outputting a printed object being the medium after performing printing on a first surface and a second surface, the control unit causes the printing unit to start printing on the first surface of the medium (P) in a nipped state in which the medium is nipped by the first nipping roller and the second nipping roller, and to start printing on the second surface on the medium in the nipped state after printing on the first surface.
