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.
