ABSTRACT:
A non-impact type of printer includes multiple ribbons and multiple printer heads so as to allow use of different types of printing technologies without requiring a user to manually change ribbons. In one embodiment, one of the ribbons installed in the printer comprises ordinary thermal transfer material while another ribbon provides a dye-diffusion type of transfer material. Installation of these and other types of ribbons in a single printer provides reduced cost and is more convenient and flexible than changing ribbons or selecting separate printers as needed.
