    Abstract: A printing machine comprising a processor and a memory storing computer readable instructions. The computer readable instructions are arranged to cause the processor to generate access request data for processing by an access control server, receive access response data responsive to the access request data, process the access response data to determine a first print limit indicated by the access response data, and update, responsive to processing the access response data, an access status in the memory to indicate a second print limit.

    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 being a corner edge printhead. The printhead 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 comprises transferring ink from the ribbon to the substrate when the print speed is less than 40 millimetres per second.

    Abstract: A labelling machine comprises a first motive apparatus configured to advance a label web along a label web path; an encoder arranged to output a sensor signal which is indicative of a rate of movement of said label web along said label web path; and a printer configured to print on said label web, the printer including a second motive apparatus configured to advance a print ribbon along a ribbon path. The labelling machine further comprises a controller configured to receive said sensor signal and control the second motive apparatus based on the sensor signal. The controller is configured to supply a pulsed control signal to the second motive apparatus, the intervals between pulses of the pulsed control signal being a function of a desired rate of movement of the print ribbon along the ribbon path. The controller is configured such that if the controller is controlling the second motive apparatus to advance the print ribbon at a first rate of movement having a first series of intervals between pulses, and the controller receives said sensor signal being indicative of the label web moving along label web path at a second rate of movement greater than the first, then the controller supplies a re-timed pulse to the second motive apparatus at a time which is before a next pulse defined by the first series of intervals.

    Abstract: A method for monitoring a characteristic of a printed image of a thermal transfer printer. The method comprises providing a ribbon and a substrate at a printing location of the thermal transfer printer. The method further comprises printing an image on the substrate at the printing location by transferring ink from a region of the ribbon in a printing operation, a negative image being formed on the region of ribbon. The method further comprises transporting the region of ribbon, by a ribbon transport system, from the printing location towards an imaging location along a ribbon transport path. The method further comprises when a characteristic of the ribbon transport meets a predetermined criterion, obtaining, by an image capture system, a ribbon image of the negative image. The method further comprises processing said ribbon image to generate data indicative of the characteristic of the printed image.

    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: A method of operating a transfer printer configured to transfer ink from a printer ribbon to a substrate which is transported along a predetermined substrate path adjacent to the printer. The printer comprises a tape drive comprising two tape drive motors, two tape spool supports on which said spools of ribbon may be mounted, each spool being drivable by a respective one of said motors. The printer further comprises a printhead being displaceable towards and away from the predetermined substrate path and being arranged to, during printing, contact one side of the ribbon to press an opposite side of the ribbon into contact with a substrate on the predetermined substrate path, and a printing surface. The printer further comprises a controller configured to control the tape drive to transport ribbon between the first and second ribbon spools. The method comprises controlling the tape drive to perform a ribbon movement in which ribbon is transported between first and second ribbon spools along a ribbon path, the ribbon path having a first length during a first part of said ribbon movement, and a second length during a second part of said ribbon movement, a transition from the first length to the second length being caused by a displacement of the printhead with respect to the printing surface, wherein control of at least one of the tape drive motors is based upon data indicative of the first and second lengths.
