Zebra ZD621R 4-Inch RFID Desktop Label Printer, 203 dpi, Thermal Transfer, UHF RFID, Wi-Fi 6, Bluetooth 5.3, Ethernet

The Zebra ZD621R (ZD6A142-30ERR2EZ) is a 4-inch thermal transfer desktop printer with a built-in UHF RFID encoder and factory-fitted Wi-Fi 6 and Bluetooth 5.3, for retail, healthcare, asset tracking and logistics teams that print and encode RFID labels anywhere on the network.

It prints at 203 dpi up to 104 mm wide and 203 mm per second, encodes RAIN RFID tags with Zebra’s RE40 reader/encoder, and connects over Wi-Fi 6, Bluetooth 5.3, USB, Ethernet and serial. A 4.3-inch colour touch display shows status and RFID results at the printer.

• Zebra ZD621R RFID printer (203 dpi, thermal transfer, Wi-Fi 6 / Bluetooth 5.3)
• External AC power supply with power cords (EU and UK)
• USB cable
• Empty ribbon take-up cores and two 300 m ribbon core adapters
• Quick start guide and regulatory guide

• Print and encode in one pass: the printer writes the RFID chip and prints the label face in the same job, and RFID job monitoring with a timestamped log shows what was encoded and when.
• Wireless anywhere: the factory-installed Wi-Fi 6 (802.11ax) and Bluetooth 5.3 dual radio (MIMO) lets you place the printer where the work is — a stockroom, counter or trolley — without a network cable, and print from Bluetooth handhelds.
• Speed and labels: 203 dpi at up to 203 mm/s suits shipping, inventory, garment and asset labels with standard barcodes; tear-off delivers strips of labels for batch work.
• Ribbons: it takes both 74 m Zebra ribbons and 300 m ribbons (with the included adapters for non-Zebra cores), so high-volume users can cut ribbon changes.
• Media: labels 15–118 mm wide on rolls up to 127 mm diameter, 12.7 or 25.4 mm core (larger cores with an adapter kit). Minimum RFID tag pitch is 16 mm.
• Integration: ZPL II and EPL2 are built in, and ZPL RFID commands match earlier Zebra RFID printers, so existing RFID label formats carry over.

• Cutting or peeling: this is the tear-off version. Peeler and cutter are separate options.
• HF / NFC tags: the encoder is UHF only; it does not write HF (13.56 MHz) or NFC tags.
• Very small print: for tiny text or small 2D codes on jewellery or electronics labels, the 300 dpi ZD621R is the better choice.
• Wide labels: maximum print width is 104 mm; for 6-inch labels choose an industrial printer such as the ZT421.
