Description Zebra ZT421 – 6-Inch Industrial Large Format Printer

The ZT400 Series evolves with the ZT421, a printer that combines Zebra’s legendary durability with the latest technological innovations. Built with an all-metal frame and a bi-fold door that reduces operating space by 35%, it is ideal for integration into production lines where space is at a premium.

The technological core is powered by the Link-OS operating system and the Zebra DNA suite, ensuring simplified remote management, advanced security, and seamless integration into existing workflows. The ZT421 is not only fast—reaching speeds up to 305 mm/s (12 ips)—but also extremely flexible. The side-loading material system and lighted supply paths make media changes quick and intuitive, drastically reducing downtime.

Thanks to field-installable options, such as the UHF RFID module or various media handling configurations (cutter, peeler, or internal rewinder), the ZT421 is a future-proof investment that grows with your business.
