This is often complicated by the fact that the diameter of both spools varies as the supply end is used up and the take-up end is increased
Similar limitations apply to traditional shuttle printers, where the pack rate is limited by the operation of the shuttle, which goes back and forth on each print and the length of the print can be limited by the travel of the shuttle

[0023] specific implementation plan
[0024] figure 1 An example of a thermal transfer printing system 100 is shown. System 100 includes belt 105 entrained around rollers 110 . The belt can be made of various materials such as polyimide film, engineering plastic or metal. Selection of an appropriate thickness for a given type of ribbon material can result in good heat transfer characteristics through the ribbon 105 , allowing high quality printing at high speeds, while also maintaining the durability of the ribbon 105 . A print roller 115 may be used to transport a substrate 120 , such as paper or plastic, in proximity to the belt 105 . Thermal transfer printhead 125 is adjacent to substrate 120 and is used to transfer hot melt ink from belt 105 to substrate 120 . In some embodiments, the system 100 can be reconfigured to position the substrate adjacent to the printhead 120 on the platen instead of the roller 115 .

Abstract
Methods, systems, and apparatus for thermal transfer printing, including media-encoded computer program products, including, in at least one aspect, a printing apparatus comprising: a belt capable of retaining hot melt ink thereon; constructed and arranged to retain and relative to a base rollers of a material conveyor belt; a printhead constructed and arranged to thermally transfer a portion of ink from the belt to the substrate for printing on the substrate; and a printhead constructed and arranged to heat the belt so that the belt The upper ink re-melts, flows and replaces the heating device for at least a portion of the portion of the ink that was previously transferred to the substrate before reaching the print head for the next print.
Description
Background technique [0001] This specification relates to systems and techniques for thermal transfer printing. [0002] Thermal transfer printing involves using a ribbon to carry material (such as ink) to a location on the printhead where heat is then used to transfer the material from the ribbon to a substrate (such as paper or plastic). Many different variations of this general process have been developed over the past six decades, and various improvements have been made in the configuration and control systems used in thermal transfer printers. For example, U.S. Patent Publication No. 2013 / 0039685 describes a motor control system, a method of operating a motor control system, a tape drive comprising a motor control system, a method of operating such a tape drive, and a printing apparatus comprising such a tape drive, When used with thermal transfer printing. [0003] In spool-to-spool printers, the ink is supplied in the form of ribbon wound on a core, which is mounted o...
