The Zebra ZT411 is an industrial thermal-transfer label printer built for demanding, high-volume label printing. This configuration is a 4-inch, 203dpi model for the US market (US power cord) with an on-metal RFID variant, and includes Serial, USB, 10/100 Ethernet, Bluetooth 4.1/MFi and USB Host connectivity. On-metal RFID encoding is specifically for tags designed to remain readable when applied directly to metal assets, which normally interferes with standard RFID performance — making this printer well suited to asset-tracking programmes tagging metal equipment, tools or infrastructure, alongside general warehouse and manufacturing label printing.
