Provided is a printing apparatus that includes a support unit which has a support surface for supporting a medium and moves in a movement direction, and a print unit configured to perform printing on the medium supported by the support unit. The support surface includes a first side and a second side that is shorter in length than the first side and extends in a direction intersecting with the first side. The support unit can be displaced to be in a first state where the first side is so arranged as to be along the movement direction and in a second state where the first side is so arranged as to be along a direction intersecting with the movement direction.

A medium feeding apparatus includes a feeding portion that performs a feeding operation, which feeds a medium to a downstream side, and a reverse feeding operation, which feeds the medium to an upstream side, and a wind-up portion that performs a wind-up operation, which winds up a medium fed to the downstream side by the feeding operation, and a unwinding operation that unwinds the wound up medium, in which the wind-up portion performs the unwinding operation prior to the reverse feeding operation.

A platen disposed so as to face a printing head includes a third support portion. A second suction hole is formed in an area through which a recording medium passes at least beyond the third support portion in the width direction of the recording medium or downstream of the third support portion in the conveyance direction. A supply port is formed between the third support portion and the second suction hole. Air is sucked into the second suction hole and supplied toward the recording medium through the supply port.

A printer includes: a platen configured to allow a rolled first recording medium and a sheet-like second recording medium to be placed thereon; and a guide table detachably provided on a base member and configured to guide movement of the second recording medium. The platen includes a first platen on which the first recording medium and the second recording medium are placed, and a second platen disposed ahead of the first platen, including an upper surface tilted obliquely downward from the rear toward the front, and configured to guide movement of the first recording medium. The guide table includes a placement portion including a flat upper surface which is located below the first platen and above a portion of the second platen and on which the second recording medium is placed.

A printing system includes a media transport system configured to pick a sheet of media from a media supply and transport it along a media transport path to a printing module. An image capture system positioned along the media transport path, includes an image capture device positioned to capture a digital image of the sheet of media, and a platen positioned behind the sheet of media, wherein a surface of the platen includes a non-uniform density pattern, and wherein the captured digital image includes at least one edge of the sheet of media and a portion of the platen that extends beyond the edge of the sheet of media. An image analysis system automatically analyzes the captured digital image to detect an edge position of the sheet of media by detecting a platen region that includes the non-uniform density pattern and a media region.

A printer includes a head configured to discharge a liquid onto a print target, and a platen configured to hold the print target. The platen includes multiple supports arrayed in a first direction and in a second direction intersecting the first direction, and each of the multiple supports is configured to movable between a first position and a second position different from the first position.

A printer for printing on rolled paper includes an air pressure sensor that detects air pressure, a platen that has a suction hole and is installed on a transport path of the rolled paper, a suction fan that sucks the rolled paper via the suction hole, and a control section that performs control for changing a rotation speed of the suction fan according to a detection result of the air pressure sensor.
