Further, the printing apparatus includes a controlling unit configured to control a blowing amount from each of the plurality of air blowing ports according to the width of the medium detected by the medium width detector.

A printing apparatus includes a transportation roller that transports recording paper in a transporting direction, a head that performs printing on the recording paper, a cutter that has a second blade located at a position facing an opening located downstream in the transporting direction of the head and the transportation roller and a first blade configured to move from the opening to the second blade and configured to cut the recording paper together with the second blade, and a flap that has a shutter configured to open and close the opening and is configured to move between a first position and a second position, and when the first blade moves from the opening to the second blade, the flap moves from the first position to the second position, and the shutter opens the opening, and when the first blade moves away from the second blade, the flap moves from the second position to the first position, and the shutter closes the opening.

An arrangement in communication with a printer. The printer includes at least a print-head configured to deposit liquid ink on an area on a surface of a substrate. The liquid ink comprises a solvent portion and a dry content. The arrangement comprises at least one nozzle configured to generate a stream of gas over said area with a gas stream velocity and/or gas stream shape, such that an evaporation rate of the solvent portion of the liquid ink is increased and a rate of change of velocity of the gas stream propagation increases with a distance normal to a direction of a gas flow and is maximized over the surface of the substrate and the deposited ink.

A printing apparatus includes a conveyance unit configured to convey a sheet along a conveyance path, a printing unit configured to print an image by discharging ink to the sheet conveyed by the conveyance unit, a heating unit configured to, in a heating section on the conveyance path, heat the sheet on which the image has been printed by the printing unit, and a control unit configured to control the heating unit so that the heating section is changed in accordance with a print condition.

An inkjet recording apparatus includes an ink jetter that jets ink and a transfer unit that has a ring-shaped intermediate transfer body. The transfer unit transfers, to a recording medium, a primary image formed on an outer circumferential surface of the intermediate transfer body with the ink that is jetted to land on the outer circumferential surface by the ink jetter. The transfer unit includes a heater that heats air in an internal space of the intermediate transfer body enclosed by an inner circumferential surface of the intermediate transfer body, and an air mover that flows the air in the internal space.

A conveying device includes a restrictor disposed at a predetermined distance from a surface of a sheet material conveyed along a sheet-material conveyance path.
