ABSTRACT:
A construction of thermal print head is disclosed in which a common support includes a plurality of substrates on which selectively heatable print elements of a plurality of print heads are carried. The substrates are arranged in spaced parallel relation such as to permit deposition of conductors and insulation layers on a face of the substrates. Print element selection and drive circuits may be mounted on the substrates and a printed circuit multi-conductor ribbon cable provides connections to the print heads. The print heads print serially on an item and may be operated to print different portions of a print impression in the same color with one print ribbon or may print differently colored portions with different colored ribbons. The thermal print head may be used for printing a franking impression in a postage franking meter.
