ABSTRACT:
A high-resolution thermal printhead and method of fabrication is provided. The printhead is of laminated construction in which densely packed circuitry required to achieve high resolution print is separated from other circuitry not requiring such dense packing. Therefore, the expensive fabrication processes required to produce the fine, high-resolution circuitry are limited to such circuitry, while less expensive fabrication processes are used to manufacture all other portions of the printhead.
