Abstract
An arrangement for activation of a thermotransfer print head has a unit to determine a transport delay and a unit to generate supplementary heating pulses to maintain a temperature required for printing at the thermo-printing heating elements. The unit to determine a transport delay is connected with the thermotransfer print head via the unit to generate supplementary heating pulses. A method for activation of a thermotransfer print head includes the steps of determining a transport delay and generating supplementary heating pulses for maintenance of a temperature necessary for printing at the thermo-printing heating elements for which a printing requirement is present.
Claims15
For a thermotransfer print head having a plurality of thermo-printing heating elements that are individually activatable to print information on a medium transported passed said thermotransfer print head, the improvement of an arrangement for activation of said thermo-printing heating elements of said thermotransfer print head comprising:
- a unit that determines a transport delay in transporting said medium relative to said thermotransfer print head;
- a unit that generates supplementary heating pulses to maintain a printing temperature at said thermo-printing heating element;
- and
- said unit for determining a transport delay being connected to said thermotransfer print head through said unit for generating supplementary heating pulses.
A method for activating respective thermo-printing heating elements of a thermotransfer print head to print information on a print medium being transported passed said thermotransfer print head, said method comprising the steps of:
- automatically electronically determining an occurrence of a transport delay in transport of said print medium passed said print head;
- and
- dependent on determination of said transport delay, automatically electronically generating supplementary heating pulses to maintain a temperature at thermo-printing heating elements in said thermotransfer print head for which a printing requirement exists.
