摘要:
A thermal printhead has heating elements arranged for multiplexing so as to limit the number of leads required to selectively energize the heating elements. Current diverting resistors are utilized to act as a shunt path to divert current from certain of the heating elements to prevent unwanted shadows from being produced on the thermal sensitive paper.
