An algorithm is disclosed which detects cyclic paths in a singly-linked list. By utilizing the algorithm many overlays may be nested and merged together. (Image Omitted) An overlay is a series of print objects which are stored in the printer's memory and when called up will print stored print objects such as text, graphics, images and bar codes. This is important when the printer is required to print the same print objects repeatedly on different pages such as is necessary when printing a series of forms. By having an algorithm to control the output, a whole series of overlays and data may be combined, and the entire data stream may be controlled by a simple host directive rather than resending the data stream multiple times.
