Standard sizes: "1-up" 8.5x5.5 (statement size) or "2-up" 8.5x11 Stock Sizes Ready for Immediate Shipment Traditional laser printers with toner cartridges give off a great deal of heat which is tough on label stock. Instead, we suggest you use a Xerox® Phaser® 8560 DN (Duplex Networked) cut sheet printer. The 8560 performs at much lower temperatures, uses "solid ink" which is toxin-free, is a very environmentally-conscious way to print and lower in cost than traditional toner.
