摘要：In a method and an arrangement for controlling printing by a thermotransferprinting apparatus with relative movement between a thermotransfer print head and aprint medium, a microprocessor that provides pixel energy data to a pixel energy

memory by making an energy value calculation and by coding, and a print data controllerprepares the pixel energy data by decoding during the printing in a number

(corresponding to the pixel energy value) of binary pixel data each with the same binaryvalue. The print data controller includes at least one pixel energy data preparation unit, aDMA controller, an address generator, a printer controller and a phase counter. TheDMA controller allows an access to the pixel energy data stored in the pixel energymemory as code in order to provide the pixel energy data in print columns to the at leastone pixel energy data preparation unit. The address generator generates addresses forselection of the buffered code during each phase of a number of phases. The phasecounter supplies a phase count value to a phase data preparation unit in which the codevalue A and phase count value B are compared in order to generated binary pixel data,which are serially supplied from the output D to at least one shift register of thethermotransfer print head.
