A new level of performance, versatility and ease of use

Configure your way with multiple connectivity options

The ZT421 comes standard with Ethernet, Serial, USB, dual USB Host and Bluetooth 4.1. Add the optional dual-band wireless card with 802.11ac Wi-Fi and Bluetooth for blazing fast and reliable wireless connections.

Built to handle a wide range of media and applications

You can count on the ZT421 to print a variety of different label formats on a variety of different media types. The printer is offered in both 4 in. and 6 in. models, with 203 dpi, 300 dpi and 600 dpi* (600 dpi available on 4 in. ZT421 only). Add factory- or field-installable RFID technology to print and encode labels for greater tracking abilities and deeper visibility. Select Zebra’s exclusive ZT421 RFID On-metal Tagging Solution, which is the only dedicated option for printing and encoding thicker RFID labels for metal containers and assets.

Dual USB Host ports for added flexibility

Dual USB Host ports allow you to directly connect a wide range of USB device types. Use a memory stick to replicate firmware, files and configurations, or easily print and transfer formats. Simplify data entry by simultaneously connecting a scanner and keyboard — with two host ports, there’s no need to plug and unplug peripherals.

Designed to evolve with your needs

You can customize the ZT421 with a range of media handling options that can be installed in minutes. Two open media slots accommodate additional communication options. And, the robust processing power and memory can support firmware upgrades and new Print DNA tools for years to come.

Effortless to integrate and operate

Large color touch display makes operation a snap

It’s easy to set up and use the ZT421 with its intuitive icon-based interface. The 4.3-inch full-color touch display allows you to quickly navigate printer settings with the user friendly icon menu system to change languages, printer settings, connectivity options and more. See color-coded alerts from a distance when the printer is paused or in an error state, so you instantly know what the printer needs to stay up and running.

Backward compatible with virtually any existing printer

Whether you are using a Zebra or competitive printer, you can use the same label formats and applications with the ZT421. Support for both EPL and ZPL makes it easy to migrate from another Zebra desktop printer. With the Virtual Devices app, the ZT421 can use languages normally associated with other printer brands.

Easy media and ribbon loading

The side-loading supplies path makes loading simpler, faster and more intuitive. The color-coded media path guides you on how to thread the media and ribbon through the printer, while lighted paths make it easy to see, even in poorly lit environments.
