ABSTRACT:
A printing apparatus includes a print roller, a platen roller and an ink roller mounted between a pair of upright supports secured to a support surface. The platen roller is resiliently biased against the print roller, and is preferably supported independently of the upright supports by a spring-biased lever and cam assembly. The printing apparatus is especially constructed for printing accordian arrays of cards, having delicate masking material thereon, and includes a feed tray with a feed stop and a take-up tray with a take-up stop each located at a position within a defined ratio with respect to the length of a single card in the array. The platen roller is preferably biased within a selected range to prevent damage to the masking material. A drive mechanism rotates the print roller which, in turn, drives the platen roller either by direct pressure or through gears.
