A popular 4-inch desktop label printer that prints crisp labels with no ribbon, set up over USB with a modular connectivity slot so you can add Ethernet or Wi-Fi later as your labelling grows.
The Zebra ZD420 is Zebra's popular 4-inch desktop label printer, built for businesses that want fast, reliable on-demand labelling in a compact, modern design. This is the direct thermal model with USB, which prints using heat-sensitive label stock alone, so there is no ribbon to buy, load or replace.
It prints crisp text, barcodes and logos at 203 dpi and up to 152mm/s (6 ips), across labels up to 104mm (4.09 in.) wide. Zebra's OpenAccess design makes media loading quick and jam-free, while dual media sensors handle a wide range of label and tag stock. It speaks both ZPL and EPL and runs on Link-OS, so it drops straight into existing Zebra label formats and barcode software.
The standout feature is the modular connectivity slot, which future-proofs the printer so you can start on USB today and add Ethernet or Wi-Fi later without replacing the unit. As a direct thermal printer it needs labels only and is best for short-to-medium-life labels. It is ENERGY STAR qualified and backed by a 24 Months Return to Base warranty.

This listing is the ZD420 Direct Thermal model, which prints with labels only and needs no ribbon. Zebra also offers a ZD420 Thermal Transfer version that uses a ribbon to produce durable, fade-resistant labels for long-life applications. Both share the same 203 dpi resolution, 6 ips speed and 104mm print width, so the choice comes down to running cost and label durability: choose this direct thermal model for the lowest running cost and short-to-medium-life labels such as shipping and product labels, or the thermal transfer model when you need long-life, fade-resistant labels. The modular connectivity slot on the ZD420 lets you add Ethernet or Wi-Fi later, and if you need a higher-spec desktop printer with more built-in options, the Zebra ZD620 is the premium step-up in the range.
