  • Thermal print head high-speed driving apparatus and method
    Patent number: 6606108
    Abstract: A thermal printer head high-speed driving apparatus positioned between a microcomputer and a thermal printer head. The apparatus stores driving history information of thermal cells in the thermal printer head corresponding to a previous line and a line before last, the driving information of the current cell of a present line to be printed and driving information of adjacent thermal cells preceding and following of the current cell. Using the stored information the high-speed driving apparatus derives drive time data for controlling an on-time of the current cell, thereby individually controlling each thermal cell of the thermal print head.
