Abstract

This article relates generally to thermal printheads and, more particul to multi-dot thermal printheads which also carry the logic used for energizing the individual dots. Still more particularly, the article relates to a general interface which permits rapid control of any dot using only four lines. Logic including a shift register is integrated on a wide (e.g., 8 1/2") multi-dot (e.g., 2000 dots) printhead.
