A printer includes: a transfer unit configured to transfer printing paper in a printing direction; a printing unit configured to print information on transferred printing paper; a detection unit installed to face discharged printing paper on a printing paper discharge portion side, and configured to acquire measured values by detecting light while printing paper is transferred or when the transfer of printing paper is stopped; and a control unit configured to collect measured values of the detection unit while printing paper is transferred, to calculate a reference value by using the collected measured values, and to determine whether printing paper has been removed by comparing the calculated reference value with a measured value acquired by the detection unit when the transfer of printing paper is stopped.

A printing apparatus includes: a print head; a main body having an accommodation part accommodating a printing medium; an opening/closing cover supported by the main body to be swingable between a closed position and an opened position, the opening/closing cover covering the accommodation part in a case the opening/closing cover is in the opened position, the opening/closing cover opening the accommodation part in a case the opening/closing cover is in the opened position; a support member provided to the opening/closing cover; and a platen holder provided to the support member and configured to rotatably support a platen roller, the platen roller being configured to convey the printing medium at a position facing the print head in the case the opening/closing cover is in the closed position.

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.

Described herein are novel printer adapters and systems and methods thereof that include techniques and structures for converting a desktop or compact printer configured to print onto rolls of media into a desktop or compact printer configured to print onto fanfolds of media. In other words, described herein are novel printer adapters and systems and methods thereof for converting a roll printer to a fanfold printer.

An image forming apparatus, having a housing, a tray detachably attachable to the housing and having a storage to store a sheet-formed medium, an image forming device to form an image on the sheet-formed medium, a conveyer assembly to convey the sheet-formed medium from the storage along a conveyer path, and a cutter to cut the sheet-formed medium at a predetermined position in the conveyer path, is provided. The conveyer assembly includes a feeder roller to feed the sheet-formed medium from the storage to the conveyer path, and an intermediate roller pair arranged in the conveyer path between the feeder roller and the image forming device. The intermediate roller pair is supported by the housing and is configured to nip the sheet-formed medium. The predetermined position is located in the conveyer path between the feeder roller and the intermediate roller pair.

A supply device for a roll medium includes a drawer-type lower holding unit configured to support a shaft of a roll medium to hold the roll medium, and a guide member configured to be pressed in a direction toward the shaft from below to come into contact with the roll medium held by the lower holding unit, and be displaced in accordance with a change in an outer diameter of the roll medium. In addition, the lower holding unit is configured to be drawn from a main body of the supply device in a first direction. When the lower holding unit, in a drawn-out state, is stored in the main body of the supply unit, the guide member comes into contact with the roll medium. The guide member is caused to be retracted downward from a travel path of the lower holding unit against a force pressing upward from below.

Included are a rolled-paper accommodation unit configured to accommodate rolled paper; a thermal head that performs printing on recording paper pulled out from the rolled paper; a control unit configured to control the thermal head; an apparatus case in which the rolled-paper accommodation unit and the control unit are provided, the apparatus case having a first edge forming a discharge opening through which the recording paper on which the thermal head performed printing is discharged; and an opening/closing cover opening or closing the rolled-paper accommodation unit and having a second edge that faces the first edge to form the discharge opening when the opening/closing cover closes the rolled-paper accommodation unit. The rolled-paper accommodation unit is provided between the first edge of the apparatus case and the control unit.

In an example of the disclosure, first and second print jobs are received at a printer. The first and second print jobs each include production frames. The first and second print jobs are printed with a media roll change occurring during printing. A first finishing device information nonproduction (“FDIN”) frame and a second FDIN frame are printed. The first and second FDIN frames include coded information regarding the first print job and the second print job, respectively. The coded information is for reading by a scanner at a finishing device. A press calibration nonproduction (“PCN”) frame that includes a printer calibration diagnostic is printed. A scanner at the printer is caused to capture the printer calibration diagnostic. A calibration operation is performed at the printer utilizing data or attributes captured from the printer calibration diagnostic.

A printer includes a rolled paper holder that accommodates rolled paper wound with recording paper having a recording surface and an adhesive surface provided on a side opposite to the recording surface, a platen roller that comes into contact with the adhesive surface and draws and feeds the recording paper from the rolled paper, a thermal head that performs printing on the recording surface, and a first guide portion that comes into contact with the recording surface and guides the recording paper, and the first guide portion has a first friction reduction portion that reduces a friction force generated between the recording surface and the first guide portion.

The present invention provides a printer station for a vehicle comprising: a housing having a top surface member connected to two side members forming an interior housing channel, a printer sliding tray, and a vehicle mounting bracket wherein: the interior housing channel is designed to contain at least a portion of the printer sliding tray; each of the two side members of the housing includes a slide feature that accepts and allows the printer sliding tray to slide in and out of the interior housing channel; the vehicle mounting bracket is attached to the housing; the vehicle mounting bracket includes vehicle attachment features for attachment to a vehicle's interior; the printer tray is designed to contain a printer; and the printer tray includes a printer paper roll holding feature to contain a printer paper roll that feeds into the printer.
