Proven durability and versatile UHF RFID encoding for wide industrial labels.

The Zebra ZT421 RFID printer/encoder combines the rugged ZT400 Series platform with integrated, factory- or field-installable UHF RFID and a 6.6-inch print path. It supports mid- to high-volume compliance, pallet, shipping, asset and item-level labeling.

A 4.3-inch color touch display, Zebra DNA for Printers and Link-OS simplify operation and remote management. Adaptive Encoding Technology supports variable inlay placement, while 203- and 300-dpi configurations balance throughput and detail.

Wide-Format RFID Performance

Print and Encode With Ease

Adaptive Encoding Technology simplifies calibration and supports a minimum 0.6-inch tag pitch. The encoder supports UHF EPC Gen 2 V2.1, ISO/IEC 18000-63 and RAIN RFID.

Large Labels at Production Speed

A 6.6-inch print width supports compliance, pallet, shipping and asset labels, with up to 12 ips output and an optional 300-dpi configuration for finer text and graphics.

Built for Industrial Work

Rugged, Operator-Friendly Design

A metal frame, metal media enclosure, side-loading supplies path and illuminated guides support demanding production environments. The bi-fold door reduces overhead clearance.

Flexible Media Handling

Continuous, die-cut, notched and black-mark media are supported, with optional cutter, peeler and liner take-up configurations.

Easy to Integrate and Manage

Connected by Design

Standard Ethernet, serial, USB, dual USB Host and Bluetooth connect the printer to common workflows; optional wireless and Industrial Ethernet capabilities extend deployment choices.

Zebra DNA for Printers

Link-OS and Zebra DNA tools support configuration, deployment, security and remote fleet management, while Print Touch NFC and dynamic QR codes speed access to help.

Application Fit

Track More Than a Barcode

Use the ZT421R for manufacturing, transportation and logistics, retail and healthcare workflows that require large printed labels plus encoded RFID data.

Qualify RFID Supplies

RFID tags must match the selected inlay placement, encoding configuration and application surface. Zebra-certified supplies help protect print quality and printhead life.

Zebra-compatible barcode labels and ribbon
