Our verdict

A compact thermal printer for shipping and mailing labels. Thermal transfer needs a ribbon, and the copy and scanner fields in the listing do not apply.

Overview

Not an office document printer, this Zebra is a desktop thermal label printer that prints by thermal transfer with a ribbon, or direct thermal on suitable media with none. It connects by USB or Ethernet.

Choose it for running address, shipping, mailing, file folder and barcode labels from a desk. The ribbon is a separate purchase for thermal transfer, and the listing's copy speed and scanner entries are errors for a print-only device.

Who it's for

A desk that prints shipping labels, name tags or file folder labels on rolls suits the label width and network port. Buyers who want a printer for documents, or a wider label, should choose another device.

Pros and cons

Pros
  • Thermal transfer and direct thermal modes
  • USB and Ethernet connections
  • Energy Star approved
  • Print speed of five inches per second
Cons
  • Ribbon needed for thermal transfer
  • Copy and scan fields do not apply
  • Print only, monochrome
  • Media roll size limits apply

Performance notes

Heat from the print head transfers ink from a ribbon to the label, or darkens direct thermal media, so the label quality depends on matching ribbon and media. Print speed tops out at the listed rate, and resolution is fixed. The rolls must fit the listed core, diameter and width limits.
