Abstract
A thermal printer apparatus is disclosed which includes a print head having a plurality of groups of thermal pixels. The thermal pixels in each group are simultaneously addressed in parallel. Each group is addressed a plurality of times. The apparatus selectively energizes the thermal pixels of each group when they are addressed until each thermal pixel is at a temperature where it can supply energy to a carrier member which delivered an amount of dye to a receiver which corresponds to a desired dye density in an image pixel.
