A housing is provided with a sheet ejection port for discharging sheet that passed through a printing unit upward. A cutting unit is arranged between the printing unit and the sheet ejection port and cuts the sheet by either a method of cutting the sheet in the entire width direction or a method of leaving the central portion of the sheet in the width direction. First protrusions and second protrusions protruding from the inner periphery of the sheet ejection port are provided at a plurality of locations along the width direction of the sheet. The first protrusion faces a first surface of the sheet and the second protrusion faces a second surface, which is the back surface of the first surface of the sheet. The first protrusion and the second protrusion are provided at positions deviated from each other in the sheet width direction and bend the sheet in an undulating shape in the width direction therebetween. Further, protrusion height of at least one of the first protrusions and the second protrusions in the central portion in the width direction of the sheet is lower than protrusion heights of the first protrusions and the second protrusions in other regions.

There is provided an image recording apparatus including: a conveyer configured to convey a sheet in a conveying direction; a head configured to discharge a liquid toward the sheet; a heater configured to heat the sheet and/or the liquid on the sheet; a reader positioned downstream in the conveying direction of the heater, the reader being configured to read an image, on the sheet, formed by the head and the heater; and a holder positioned between the reader and the heater in the conveying direction, the holder being configured to hold a body of rotation configured to contact a recording surface of the sheet. In a crossing direction orthogonal to the conveying direction and crossing the recording surface of the sheet being conveyed by the conveyer, both ends in the crossing direction of the holder are positioned outside of both ends in the crossing direction of the reader.

A printing apparatus includes: a cap member configured to be switched between a capped state in which an ink discharge port of a printhead is covered by the cap member and a non-capped state; a conveyance unit configured to convey a print medium to the printhead; and a cutting unit configured to cut the print medium on which an image is formed by the printhead. A cutting setting for operating the cutting unit can be set in advance based on a cutting instruction of a user. In a case in which the cutting setting is set, the cap member waits for the cutting instruction in the non-capped state, and the cap member is switched to the capped state when a wait time for the cutting instruction reaches a predetermined time.

A printing device includes: an image recording unit configured to record an image on a printing medium; a cutter unit configured to cut the printing medium on which the image is recorded by the image recording unit; and a medium receiving unit configured to receive the printing medium on which the image is recorded by the image recording unit. The cutter unit is positioned frontward of the image recording unit in a frontward direction. The medium receiving unit is positioned below the cutter unit at a time of an image recording operation and being detachable in the frontward direction.
