Panduit Laser Labels are designed to function in most desktop laser printers. Polyester materials are provided on a clear liner to assure clear movement throughout your printer's paper path. Most Panduit Labels are intended for flat application labeling, with the exception of Self-Laminating Polyester Labels (GMY3) and Permanent Polyolefin Labels (GMPO). All labels can also be used in a wide variety of copiers. If you need to make many copies of the same label, a copier might be the quickest solution.
