The pair of supporting rollers are disposed on both sides of the central axis of the rolled medium when viewed in the axial direction of the rolled medium. The pair of restricting members are disposed outside a space between the pair of supporting rollers in a circumferential direction of the rolled medium, and are respectively adjacent to the supporting rollers, and are provided so as to be movable independently from each other.

A printing apparatus including a roll paper accommodating unit configured to accommodate roll paper, a single sheet paper accommodating unit configured to accommodate single sheet paper, a printing unit configured to perform printing on the roll paper fed from the roll paper accommodating unit, and to perform printing on the single sheet paper fed from the single sheet paper accommodating unit, and a main body frame that supports the single sheet paper accommodating unit and the roll paper accommodating unit, in which the roll paper accommodating unit and the single sheet paper accommodating unit are located in ranges, in a front-back direction of the printing apparatus, overlapping a range in which the printing unit is present, and are located downward of the printing unit with respect to a vertical direction, and the roll paper accommodating unit and the single sheet paper accommodating unit are movable frontward of the printing apparatus.

An apparatus includes a first drive unit configured to rotate a roll sheet supported by a roll support unit in a predetermined rotation direction to feed the sheet into a conveyance path, an abutment portion provided so as to be capable of abutting against an outer peripheral surface of the roll sheet at a first position, and a rotation member provided so as to be capable of abutting against the outer peripheral surface at a second position. The first drive unit rotates the roll sheet in the direction to introduce, into the conveyance path, a leading edge of the sheet having passed between the first and second positions. The apparatus further includes a second drive unit configured to rotate the rotation member in a direction in which a slack of the sheet is formed between the first and second positions.

A printing apparatus includes a conveyance unit including a pair of rotation members that nip a roll sheet, and configured to convey the sheet by rotation of the pair of rotation members, a printing unit, and a control unit configured to, upon executing a new print job, cause the conveyance unit to perform a preparatory operation in which the sheet is conveyed in a forward direction and then conveyed in a reverse direction and stopped. If a predetermined condition is met after completion of a previous print job, the control unit causes the conveyance unit to perform the preparatory operation, and if the predetermined condition is not met after completion of a previous print job, the control unit does not cause the conveyance unit to perform the preparatory operation.

A recording apparatus is configured to support a roll body on which a medium is wound in a rolled form, and to perform recording on the medium fed out from the roll body, the recording apparatus including a housing, and a roll unit configured to support the roll body, in which the roll unit is configured to transition to a first mode in which the roll unit is stored inside the housing in a state of not supporting the roll body, and to a second mode in which the roll unit is drawn out from inside the housing to outside the housing where the roll unit is configured to support the roll body

A printing apparatus includes: a sheet storing part configured to store a sheet; a conveying mechanism configured to convey the sheet taken out from the sheet storing part; a first frame and a second frame arranged in an opposing direction with the conveying mechanism interposed therebetween; a printing part configured to perform printing on the sheet conveyed by the conveying mechanism; a cover composing at least a part of an upstream side, of the printing apparatus, with respect to the printing part in a conveyance direction in which the sheet is conveyed by the conveying mechanism; and a rotational shaft extending in the opposing direction and configured to support the cover to be rotatable. The rotational shaft has a first end and a second end in the opposing direction, and the first end is supported by the first frame and the second end is separated away from the second frame.

An example thermal printhead apparatus includes a top end; a bottom end located opposite the top end; an electrical interface positioned proximate to the bottom end; a first distal end; a second distal end located opposite the first distal end; a printing face defined by the top end, the bottom end, the first distal end and the second distal end, the printing face includes a thermal element; a mounting face that is opposite the printing face, the mounting face defined by the top end, the bottom end, the first distal end and the second distal end, the mounting face including at least two mounting components, comprising: one or more holes configured to mount the printhead apparatus to a printer; and one or more grooves configured to mount the printhead apparatus to a printer, the one or more grooves extending substantially parallel to the top end and the bottom end.

A liquid discharging apparatus is provided capable of preventing liquid from being discharged onto a medium to which any foreign substances adhere. A printing apparatus (10) (liquid discharging apparatus) includes a holding member (21) configured to hold a roll body (R1) on which a medium (M) is wound, a transport unit (40) configured to transport the medium (M) fed from the roll body (R1) held by the holding member (21) along a transport path (FP), a discharging unit (61) configured to discharge liquid onto the medium (M) transported by the transport unit (40), and a vibration unit (34) configured to apply vibration to the medium (M) being transported from the holding member (21) to the transport unit (40). In the transport path (FP), a path on which the medium M to be subjected to vibration by the vibration unit (34) is transported is referred to as a vibration transport path (FP1), and the vibration transport path (FP1) is configured to extend vertically upward as approaching from the holding member (21) to the transport unit (40).

A printing system includes a feeding mechanism adapted to feed substrate from a substrate roll to a print zone, the feeding mechanism including a roller with an associated encoder configured to provide an encoder signal. A printhead is located in the print zone, and a controller configured to receive the encoder signal from the encoder, and to correlate the encoder signal to a substrate type.

There is provided a print apparatus and a media roll for the print apparatus, comprising a media identifier located on an end of a core section of the media roll. A type of media loaded into the print apparatus is determined by sensing the media identifier on the media roll using a non-contact sensor to scan the end of the core section.
