Abstract: A method of operating a thermal transfer printer, the thermal transfer printer comprising first and second spool supports (3a, 4a) each being configured to support a spool of ribbon (3,4); a ribbon drive (3b, 4b) configured to cause movement of ribbon from the first spool support to the second spool support along a predetermined ribbon path; and a printhead (7). The printhead (7) 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 (V-substrate). The method comprising causing relative movement between the ribbon and the printhead at a ribbon speed (V-ribbon). 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 (F-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 labelling machine comprises a supply spool support for supporting a spool of label carrying web, a take up spool support adapted to take up a portion of web, and a first motive apparatus for transporting web along a web path between the supply spool support to the take up spool support, and a controller. The controller is configured to provide a control signal to the first motive apparatus, wherein the controller is further configured such that the controller provides a control signal to the first motive apparatus to accelerate the first motive apparatus between a first speed and a second speed by providing a control signal to the first motive apparatus to command the first motive apparatus to accelerate to a predetermined first intermediate speed intermediate the first and second speeds, then a control signal to command the first motive apparatus to accelerate to a second predetermined intermediate speed intermediate the first intermediate speed and the second speed, and then a control signal to command the first motive apparatus to accelerate to the second speed.

Abstract: A method for controlling a thermal printhead of a printer. The printhead comprises an array of printing elements. The method may comprise performing a plurality of printing operations, each printing operation comprising energization of one or more printing elements. A respective energization value is determined for each printing element based upon energizations of that printing element during said printing operations. A printhead control signal is generated for the printhead for a subsequent printing operation based upon the energization values of a predetermined subset of the printing elements.
