Zebra ZD421 – a label printer that keeps up with a busy working day

The Zebra ZD421 is built to handle the demands of everyday professional use. Its cartridge-based thermal transfer system keeps print quality consistent across labels, price tags and product markings — and because the cartridge swaps out quickly and cleanly, you won't lose momentum in the middle of your busiest hour.

Sharp enough for barcodes, fast enough for batches

At 203 dpi (8 dots per millimetre), the ZD421 handles barcodes, text and simple graphics without compromise. Print speed reaches 152 mm per second, so even a run of labels clears in reasonable time. Maximum print width is 104 mm and media width goes up to 118 mm, covering the most common label stock sizes used in retail and workshop settings.

Connections that fit your setup

The ZD421 ships with a full set of connection options so it works however your counter or stockroom is organised:

• ·USB (Type B) and USB Host — plug directly into a PC or connect via a host device
• ·Bluetooth Low Energy (BLE) — wireless link to a phone or tablet on the floor
• ·Ethernet — fixed network connection for a shared printer that several staff members use

The printer supports EPLII, ZPLII and XML emulation, which means it slots into most existing systems without a lengthy configuration project.

Timestamps without extra software

The built-in real-time clock (RTC) lets you print timestamps directly from the device — no separate software required. Particularly useful in food service or warehouse environments where recording the time of production or packing is a daily requirement.

Wipe-down housing for environments where cleanliness matters

The housing is designed to withstand regular wiping and disinfection, making it a practical fit for healthcare-adjacent or food-handling settings where hygiene standards are non-negotiable. Black Mark Sensor and Gap Sensor work together to find the start of each label automatically, so you don't waste material on misfeeds.

What's in the box

The ZD421 comes with a USB cable, power supply unit and power cables for both EU and UK outlets. Warranty is 36 months. Country of origin: CN.

If you need a reliable desktop label printer that connects in minutes and runs without fuss — plug in the cables, install the driver, and you're printing.
