A printing device includes a base plate extending in a direction orthogonal to a first direction, a mounting portion provided rotatably on a surface, which is at one side in the first direction, of the base plate, in which a ribbon roll having an ink ribbon wound is to be mounted on the mounting portion, a thermal head provided on the surface of the base plate, and configured to perform printing on a printing medium disposed on one side in a second direction orthogonal to the first direction; and a printed circuit board located on one side, with respect to the base plate, in a third direction orthogonal to the first direction and the second direction, and extending in a direction intersecting the base plate.

An enhanced paper for printing, including a substrate, an ablation resistant coating applied to the substrate, wherein the enhanced paper is ablation resistant so that it is not damaged by a light beam that illuminates enhanced paper with a fluence that ablates ink or toner but would damage standard printing paper that is made from cellulose fiber and is non-ablation resistant; and wherein the enhanced paper has physical properties of the standard printing paper for printing with laser printers and ink printers.

A printer according to an embodiment includes: a printer body including a supplying part that rotatably holds a roll-shaped sheet member; an opening and closing cover configured to open and close with respect to the printer body; a thermal head disposed on the printer body, the thermal head configured to print on the sheet member; a platen roller disposed on the opening and closing cover, the platen roller positioned at a location opposite to the thermal head and feeding the sheet member in a closed configuration; and a platen roller holding mechanism configured to attachably and detachably secure the platen roller to the opening and closing cover. The platen roller holding mechanism includes a label roll supporter that rotatably guides the roll-shaped sheet member in the supplying part. The label roll supporter includes a cross-sectional arc-shaped surface.

A decoloring apparatus includes a sheet conveying unit, a scanner, a decoloring unit positioned downstream of the scanner, a user interface, and a controller. The user interface includes a resolution setting section configured to receive input for setting the resolution of the image to be scanned by the scanner, and a processing mode setting section configured to receive input for setting whether to execute scanning processing by the scanner and for setting whether to execute decoloring processing by the decoloring unit. The controller is configured to control contents of the user interface and to perform a mode limiting processing so that when one of the scanning processing and decoloring processing is set to be executed, the other of the scanning processing and decoloring processing cannot be set to be executed.

A thermal printer includes a platen roller, a thermal head, a head support plate, a frame including a platen roller support portion, a turn support portion configured to support the head support plate, and an urging member configured to urge the head support plate in a direction in which the thermal head approaches the platen roller. The thermal head is fixed to an opposed surface of the head support plate, which is in a first region located on one side with respect to the turn support portion, and is opposed to the platen roller in the first direction. The urging member is interposed between the opposed surface of the head support plate in a second region, which is located on another side with respect to the turn support portion and an urging member support portion of the frame.

A thermal printer includes a frame having a first side plate portion and a second side plate portion, and a base portion which crosses over between the first side plate portion and the second side plate portion, a thermal head supported on the frame, a platen roller supported on respective shaft support portions of the first side plate portion and the second side plate portion, a drive source supported in a cantilevered state on a drive support portion of the first side plate portion, and is connected to the platen roller, an engaged portion arranged in the base portion, and an engagement portion which is connected to the drive source and is engageable with the engaged portion, and is configured to regulate displacement of the drive source with respect to the base portion.

A mobile printer includes a roll body accommodating portion accommodating a roll body on which recording paper is wound, a print head performing printing on the recording paper, a transport unit pulling out the recording paper from the roll body and transporting the recording paper, a power supply unit supplying a drive voltage signal to the print head and the transport unit, a housing covering the roll body accommodating portion, the print head, the transport unit, and the power supply unit, and a static electricity removal film, in which the power supply unit has a power receiving module receiving a signal based on a power supply voltage signal from an outside by a non-contact power supply, and at least a part of the static electricity removal film is located between the roll body accommodating portion and the power receiving module and adjacent to the power receiving module.
