Zebra ZT421
A new level of performance, versatility and ease of use for 6-inch industrial printing.
The Zebra ZT421 keeps critical labeling operations moving with durable metal construction, wide-format 6-inch output and an intuitive 4.3-inch color touch display. Choose 203 or 300 dpi and the connectivity or media-handling configuration that fits the workflow.
