Abstract: A portable printer comprises a base and a cover covering the top of the base. A print head arranged in a vertical direction and a paper feed roller provided opposite to the print head are provided in the base. The paper feed roller rotates about a first axis. The paper feed roller conveys recording paper by rotating in the state that the recording paper is clamped between the paper feed roller and the print head. An actuating rod driving the print head to be close to or away from the paper feed roller in response to an opening/closing action of the cover is provided in the base. The actuating rod is configured to swing around a second axis parallel to the first axis, and is provided with an installation part suitable for mounting the print head and a drive part suitable for being driven by the cover.

Abstract: A method of operating a thermal transfer printer, the thermal transfer printer comprising first and second spool supports each being configured to support a spool of ribbon; a ribbon drive configured to cause movement of ribbon from the first spool support to the second spool support along a predetermined ribbon path; and a printhead. The printhead is moveable towards and away from a printing surface, and, during printing, is configured to selectively transfer ink from the ribbon to a substrate as the substrate and printhead are moved relative to one another at a print speed. The method comprising causing relative movement between the ribbon and the printhead at a ribbon speed. A relative speed of movement between the ribbon and the substrate during printing is controlled based upon a force exerted upon the ribbon by the printhead during a printing operation, and/or a parameter indicative of an area of contact between a portion of the printhead and a portion of the printing surface.

Abstract: There is provided a printing apparatus including: a frame; a casing; a thermal head; a platen; a moving mechanism supported by the frame; a motor; a transmitting mechanism; a sensor detecting a position of the moving mechanism; a communication interface; and a controller. The controller is configured to: perform determination as to whether the moving mechanism is located at a reference position; perform determination as to whether a print signal is received from the external apparatus; and selectively execute one of first processing and second processing in accordance with results of these two determinations. The controller selectively executes the first processing when the moving mechanism is not located at the reference position and the print signal is received; and the controller selectively executes the second processing when the moving mechanism is located at the reference position and the print signal is received.

Abstract: 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.

Abstract: Disclosed is a thermal print apparatus including a medium detection sensor arranged from a thermal head at a distance shorter than an outer circumferential length of the platen roller, and a controller. The controller determines that the print medium is wrapped around the platen roller if the print medium is not detected by the medium detection sensor even when the print medium is fed by a feed amount at which the leading edge of the print medium reaches the medium detection sensor after starting of printing on the print medium. In this case, the print medium is fed backward by reversely rotating the platen roller.
