Abstract: A processing system according to the present invention includes a printer that receives unprocessed marker tubing stock (i.e., multiple rows of uncut and unprinted tubing mounted on a carrier) for simultaneous printing of the marker tubing and the carrier with a single print head. A cutting device is configured to sever the marker tubing rows into sections, regardless of the width of the tubing and regardless of whether there are two rows or four rows of tubing. Since the tubing has its longitudinal axes aligned with a longitudinal axis of the carrier, activation of the cutting device can be controlled to sever sections of marker tubing in varying customized widths. In the same cutting stroke, the carrier can be scored or perforated (“perfed”). A rewinder or the like then takes up the severed and perfed stock.
