摘要： An apparatus for providing back tension onto a print media web comprises a plate having a post extended perpendicularly therefrom. The post is adapted to support a roll of print media thereon such that a web of the print media roll is paid out by rotation of the roll about the post. A constant-force spring is attached to a portion of the media plate at and has a handle coupled to an opposite end of the spring. A pressing element is coupled to the handle such that the spring is biased to urge the pressing element against the media supply roll to maintain the roll firmly in contact with the post during rotation of the roll. The force provided by the pressing element onto the media supply roll imparts sufficient back tension on the print media web to maintain a constant pay out rate. The present back tension apparatus provides a relatively simple mechanism that is readily adaptable for many conventional printers, such as a thermal transfer printer.

摘要： A printer for printing on an outer layer of a print medium on a print medium roll. The printer may use thermal or inkjet printing. The printer is used without a mechanical paper drive mechanism. The printer monitors movement of an outer wrap of the print medium as the print medium roll rotates in response to a user pulling print medium from the print medium roll. In one embodiment, the printer detects movement of the print medium with a metering roller and an optical rotation sensor. In another embodiment, the printer monitors movement of the print medium by detecting movement of index marks on the print medium. From the monitored movement of the print medium, the printer identifies a portion of the print medium aligned to the printhead and selects image portions to print in the identified portion. The printer then activates the printhead to print the selected image portions in the corresponding identified portion. A bias spring, together with movable mounting of the printhead, allows the printhead to remain engaged with the print medium as the radius of the print medium roll decreases as the print medium is dispensed.

摘要： A printer for printing on an outer layer of a print medium on a print medium roll. The printer includes a base and a cover, which are pivotally coupled in a "clamshell" configuration for movement between a closed position in which the printhead is located in a printing position proximate the path of the media and an open position that is spaced from the printing position. The printer may use thermal or inkjet printing. The printer is used without a mechanical paper drive mechanism. The printer monitors movement of an outer wrap of the print medium as the print medium roll rotates in response to a user pulling print medium from the print medium roll. In one embodiment, the printer detects movement of the print medium with a metering roller and an optical rotation sensor. In another embodiment, the printer monitors movement of the print medium by detecting movement of index marks on the print medium. From the monitored movement of the print medium, the printer identifies a portion of the print medium aligned to the printhead and selects image portions to print in the identified portion. The printer then activates the printhead to print the selected image portions in the corresponding identified portion. A bias spring, together with movable mounting of the printhead, allows the printhead to remain engaged with the print medium as the radius of the print medium roll decreases as the print medium is dispensed.

摘要： A clamshell printer having a base and a cover pivotally mounted to the base for movement between an open and a closed position, wherein the open position provides unhindered access to a media path and a print head in the printer. The printer may include a platen formed integrally therein or a platen rollingly supported in the printer. A media supply, such as a continuous sheet of linerless thermal media in the form of a roll may be quickly and efficiently drop-loaded into the printer, with no threading of the media required. Unhindered access to the print head is also provided. The printer may or may not include a drive mechanism for advancing the media through the printer. The print head is controlled by a microprocessor mounted to a circuit board in the printer. The circuit board may be spring-biased to urge the print head toward a printing position, which is located at an effective printing distance from the media and the platen. A window may be formed in the printer for observing the media supply.
