Datamax-O'Neil - media retainer

The Datamax-O'Neil media retainer boosts the media tracking while making use of the narrow roller stocks that have large outside diameters. It is a piece of hardware that firmly holds the media roll in place. The accessory is designed to be compatible with the Datamax-O'Neil M-Class Barcode Label Printer and the Datamax-O'Neil H-Class Barcode Label Printer.
