Zebra ZD621 Premium 4-Inch Desktop Barcode Printer overview
The ZD621 is the high-end 4-inch model in Zebra's ZD600 desktop family. It is available as a direct thermal or thermal transfer printer and prints at up to 8 ips at 203 dpi or 6 ips at 300 dpi, making it noticeably faster than mid-range desktop models.
Ethernet, USB 2.0, USB host and serial ports are all included as standard, and dual-radio Wi-Fi 6 with Bluetooth 5.3 or Wi-Fi 5 with Bluetooth 4.2 can be ordered factory-fitted or added later. The thermal transfer version can be specified with a 4.3-inch colour touch display.
An RFID option (ZD621R) adds UHF encoding based on Zebra's RE40 reader/encoder. Zebra positions the printer for retail labelling and receipts, hospitality ticketing and wristbands, healthcare specimen and patient ID labels and government tracking labels.
