ABSTRACT:
A thermal printing system with encoded cassettes is disclosed. A thermal image transfer sheet is removably attached to a print sheet. Encoded instructions may be provided as either a bar code placed on the print sheet, as digital signals stored in a ROM or RAM storage device which forms a part of a cassette supply storing the print sheets, or as digital signals indicated by extruded pins or punched holes in a part of a cassette supply storing the print sheets. The encoded instructions represent certain conditions, such as the optimum thermal printing energy to be applied to pixels forming a printing head, and such encoded instructions are utilized to program various aspects of printing, such as the printing format. The print sheet may be divided, as by scoring, into different print fields so that it may be readily separated into separate display signs.
