The Zebra ZD621R is a desktop thermal transfer label printer with integrated RFID encoding (the "R" designation), built for businesses that need to both print and encode RFID tags at a desktop scale rather than the higher industrial volume of a floor-standing printer. This "ROW" (rest-of-world) regulatory variant prints at 300dpi with a colour touch LCD for on-device status and setup, and connects via USB, USB Host, Ethernet, Serial, 802.11ac Wi-Fi and Bluetooth 4 — a broad connectivity set suited to retail back-office, small warehouse or asset-tagging use.
