A thermal printing mechanism prints a black pattern on a paper web with a direct printing process and additionally prints a color pattern on the paper web with a transfer printing process. The paper web and a transfer film web are moved between a platen and a thermal printhead, with the transfer film web between the paper web and the printhead, with heating elements within the printhead being operated at one temperature to produce the color pattern and at another, higher temperature to produce the black pattern. Preferably, the transfer film web is moved only when the color pattern is being printed and when it is otherwise necessary to prevent the film web from being worn through as the black pattern is printed.
