Zebra's current-generation 4-inch desktop label printer for shipping, product and barcode labels, with ribbon-free direct thermal printing, Bluetooth and USB connectivity, and a modular slot to add networking later.
The Zebra ZD421 is Zebra's current-generation 4-inch desktop label printer and the modern replacement for the older GK series. This is the direct thermal model with Bluetooth and USB, and it sits as the value entry point in the ZD421 range, giving Australian businesses a dependable, future-proof printer without paying for features they will not use.
As a direct thermal printer it needs no ribbon. It prints straight onto heat-sensitive label stock, which keeps running costs low and loading simple, and it is the right choice for short-to-medium-life labels. It prints crisp text, barcodes and logos at 203 dpi and up to 152mm per second (6 ips), across labels up to 104mm (4.09 in) wide. Zebra's OpenAccess design and dual media sensors make loading quick and reliable across a wide range of label and tag stock.
Connectivity covers Bluetooth and USB out of the box, plus a modular connectivity slot so you can add Ethernet or Wi-Fi later as your needs change. It runs on Zebra's Link-OS platform with Print DNA and PrintSecure for easier management and stronger security, speaks both ZPL and EPL, is ENERGY STAR qualified, and is backed by a 24 Months Return to Base warranty.

The ZD421 is Zebra's current-generation 4-inch desktop printer and the modern replacement for the older GK series. This listing is the direct thermal model, which prints straight onto heat-sensitive labels with no ribbon, keeping running costs low for short-to-medium-life labels such as shipping and product labels. Its sibling, the Zebra ZD421 Thermal Transfer, uses a ribbon to produce durable, long-life, fade-resistant labels, which suits asset tags and labels that need to last. Both share the same 203 dpi resolution, 6 ips speed, 104mm print width, modular connectivity and Print DNA platform, so the choice comes down to label durability and running cost. For higher-volume work, the Zebra ZD620 is the premium step-up in the range.
