A printing system for printing characters in various fonts and formats onto webs of sheet stock of various sizes includes apparatus for cutting the web into various lengths to accommodate various formats as well as for providing different lengths of tags which are interposed between batches of tags to permit easy separation of the batches. A stacker is also provided which selectively stacks the tags in a shingle fashion or into piles. Circuitry is provided to detect jams in the system and to assure that the proper size web corresponding to the selected format is used. Also, the system is provided with circuitry for adjusting the line print position to compensate for positioning errors caused by mechanical tolerances in the printers.
