Abstract
A ribbon for a thermal printer has a series of frames of different colors in a sequence that are correlated to the position of cards to be printed. The ribbon has indexing marks for each frame and also indicators for each repeating sequence of frames. The index marks are arranged in a line across the ribbon and the marks can be coded to individually indicate the color or other characteristic of the frame associated with the line of index mark. This information is received by a controller to control various printer functions.
