System for energizing thermal printer heating elements |
摘要 |
A thermal printer for printing an output dye image in a receiver including a memory circuit for storing a matrix printing pattern of pixels. The thermal printer comprises a detector for detecting the level of pixels data read out sequentially from the memory circuit to determine if a pixel of a line in the output image is to be printed has adjacent pixels that are not to be printed. Circuitry is provided to receive a printing pattern from the memory and to be responsive to the detector and to cause the heating elements corresponding to such image pixel to be printed to be energized above a predetermined dye transfer threshold level and the heating elements corresponding to pixels not be printed to be energized below the threshold level.
