Zebra QLn320 Mobile Label Printer Direct Thermal, 203 dpi, 4 ips, Wi-Fi, Ethernet, Belt Clip

SKU: 

QN3-AUNA0E00-09

Equipped with IEEE 802.11n dual-radio wireless LAN alongside Fast Ethernet, Bluetooth, USB, and serial connectivity, the Zebra QN3-AUNA0E00-09 is a battery-powered mobile direct thermal printer carrying a 2450 mAh cell and 128 MB of standard memory. It prints monochrome labels at 203 dpi and up to 4 in/s across a 2.80-inch print width, accepting media up to 3.11 inches wide, 32.01 inches long, and 6.50 mil thick on rolls to 1.37 inches in diameter. NFC support enables Print Touch functionality, while CPCL, EPL, ZPL, and ZBI 2.0 emulation preserve compatibility with existing label formats. Gap, black mark, and label taken sensors handle linered, linerless, die-cut, and receipt stock, and an IP54 ingress rating keeps the 1.60 lb chassis dust and water resistant across an operating range of 32°F (0°C) to 122°F (50°C). Retail, manufacturing, and transportation and logistics deployments on PC, Android, and iOS platforms are covered by a one-year limited warranty.
