摘要： A demand printer has an input structure for receiving command signals related to the operation of the printer; a control circuit coupled to the input structure, and a power supply circuit for processing command signals and generating corresponding control signals for controlling the operation of the printer. A switch circuit line is coupled to at least a first and a second point on the power supply circuit. The switch circuit line provides a first operating voltage for the operation of the printer when connected between the first and second points in the power supply circuit and provides a second operating voltage when the connection between said first and second points is opened by a severing structure. The severing structure projects into a base cavity of the case and is retained therein for maintaining an open circuit between the first and second points on the power supply circuit once said switch circuit line is severed. The severing structure includes a wall of the base cavity which has an control aperture extending therethrough, a severing body having a head end and a severing end wherein the severing end projecting through the control aperture and contacting and severing the switch circuit line; a retaining segment on the severing body operatively associated with the case when the severing body is inserted through the control aperture for retaining the severing body in contact with the switch circuit line to maintain an open circuit between the first and second points.

摘要： A demand printer for printing on media includes a ribbon take-up spindle for accumulating spent printing ribbon and facilitating removal of the spent ribbon from the spindle. The spindle has a surface with a protrusion bore formed therethrough. At least one protruding segment extends through the protrusion bore. The protruding segment controllably projects away from the spindle surface for maintaining a space between a portion of the spindle surface and the spent ribbon accumulated on the spindle. A biasing structure is operatively associated with the spindle and the protruding segment for controllably biasedly directing the protruding segment through the protrusion bore in the spindle. A retracting structure is provided for controllably compressing and expanding the biasing means to controllably move the protruding segment through the protrusion bore.

摘要： A thermal demand printer for printing on media is a novel system which includes a case structure including a hinged cover panel, easily removable guide structures and media hanger, and a single central support wall to which the various components are attached. The printer includes a power supply circuit for receiving power from an external source and conditioning it for operation of the printer. An input device is provided for receiving command signals related to the operation of the printer. A control circuit for processing the command signals and generating corresponding control signals for controlling the operation of the printer and a printhead assembly for processing the control signals and generating corresponding control signals for controlling the operation of the printer are mounted in the case structure and coupled to the input device and the power supply circuit. The printhead assembly includes a printhead support structure which controls the printhead. A ribbon take-up spindle, method of operating the take-up spindle using a PMDC motor, and a spring wrap clutch device help to control the tension in the transfer ribbon used in the printer. The printer also includes a medial sensor and a method of sensing media by way of detecting the opacity of the media passing through the sensor. The printer includes a method of printhead control using double data loading and a method of accelerating and decelerating media relative to the printhead using pulse width modulation.
