Zebra ZT421 – Label Printer for Daily Professional Use

The Zebra ZT421 is a midrange thermal transfer label printer built to handle demanding daily workloads in stockrooms, retail back-offices, and workshops. When the job doesn't pause, neither does this printer.

Printing that keeps up with your busiest moments

At a maximum print speed of 305 mm/s, the ZT421 won't become a bottleneck when orders are stacking up or a delivery needs labelling fast. Media width reaches up to 178 mm and print resolution sits at 203 dpi — sharp enough for small barcodes and fine text that scanners actually read first time. The roll capacity handles cores up to 203 mm in diameter, so you're not swapping media rolls every couple of hours.

Colour touchscreen and real-time clock — less guessing, more working

The colour touchscreen shows printer status at a glance. You can see immediately whether media is running low or a setting has drifted, without pulling anyone away from the counter or the workbench. The built-in real-time clock (RTC) keeps print logs timestamped accurately without any manual adjustment — useful when you need to trace when a batch of labels went out.

Connects to whatever you already have

The ZT421 fits into your existing setup regardless of how your network is built:

• ·USB (×2) — direct connection to a PC or a peripheral device
• ·RS232 — backwards compatibility with older systems
• ·Ethernet — stable wired network connection
• ·Wi-Fi 802.11ax — fast wireless, including in dense network environments
• ·Bluetooth 5.3 — pairs with mobile devices and handheld terminals

No need to re-run cables or reconfigure your network just to add a label printer to the workflow.

Works with the software you're already running

The ZT421 supports EPL, ZPL, and ZPLII emulation, which means it connects directly to most warehouse management and point-of-sale systems without extra software licences or coding changes. With 256 MB RAM and 512 MB Flash on board, larger print queues clear smoothly without the printer stalling mid-job.

What's in the box — and what to order separately

The package includes a power cable with both EU and UK plugs. The interface cable is ordered separately — when you place your order, confirm which connection type matches your installation so you have the right cable on day one.
