  • Patent number: 7508404
    Abstract: A thermal printers and printing methods are provided. The thermal printer has a first thermal print head adapted to pressure a first donor web against the receiver medium and to selectively transfer donor material to the receiver medium in an image wise fashion to form a first image in an image receiving area of the receiver medium; and a second thermal print head adapted to pressure a second donor web against the receiver medium and to selectively transfer second donor material to the receiver medium in an image wise fashion to form a second image in the image receiving area. A receiver medium transport system moves receiver medium along a printing path and the first thermal print head and the second thermal print head are positioned along the path so that they can apply donor material to the receiver medium at least in part simultaneously when instructed by a controller.
