Reduce RFID Media Costs

You can count on the Zebra ZT400 Series to print a variety of different label formats on a variety of different media types. When RFID-enabled, the 4-inch Zebra ZT411 and 6-inch Zebra ZT421 can print and encode labels as small as 0.6 in./16 mm. And, the ZT411 can print up to 600 dpi for extremely crisp resolution. The Zebra ZT411 RFID, available in an on-metal version, is the only dedicated option for printing and encoding on-metal tags and labels.
