Frequently asked questions
How does the ZT42162-T0100J0Z differ from the ZT42162-T0100A0Z?
Zebra lists both with the same configuration: 6 in, 203 dpi, Serial, USB, 10/100 Ethernet, Bluetooth 4.1/MFi, USB Host and a UHF RFID encoder for the US and Canada. Zebra is ending sale of the ZT42162-T0100A0Z on November 20, 2026; the ZT42162-T0100J0Z is the part number Zebra currently sells.
What RFID tags can the ZT421R encode?
UHF tags compatible with EPC Gen 2 V2.1, ISO/IEC 18000-63 and RAIN RFID, at a minimum pitch of 0.6 in (16 mm). Adaptive encoding removes complex placement guidelines.
Can I add RFID to a standard ZT421 later?
Yes. The integrated RFID system is user-upgradable in the field on both the 4 in ZT411 and 6 in ZT421.
What is the difference between the ZT411 and ZT421?
The ZT411 prints up to 4.09 in wide at up to 14 in/s and offers 600 dpi. The ZT421 prints up to 6.6 in wide at up to 12 in/s, in 203 or 300 dpi, for larger labels such as drum and pallet labels.
What label sizes fit?
Media 2 to 7 in wide (slightly narrower for peel and rewind), with labels up to 102 in long at 203 dpi.
What roll and ribbon sizes fit?
Label rolls up to 8 in outer diameter on 3 in cores, and 1,476 ft (450 m) ribbons on 1 in cores, 2 to 6.85 in wide.
What connectivity does it have?
USB 2.0, RS-232 Serial, 10/100 Ethernet, Bluetooth 4.1 and dual USB Host come standard. Two open slots take a Wi-Fi 6 (802.11ax) with Bluetooth 5.3 card, a Wi-Fi 5 (802.11ac) with Bluetooth 4.2 card, parallel, a second Ethernet port or an applicator interface.
Which programming languages does it support?
ZPL and ZPL II, compatible with all Zebra printers, plus EPL 2 on 203 dpi models and optional ZBI 2.0.
What warranty does it have?
Zebra warrants the ZT421R against defects in workmanship and materials for 1 year from shipment. Zebra OneCare plans extend coverage and can add printheads, normal wear and accidental breakage.
