About
Zebra ZT421 – a label printer that keeps up with your working day
The Zebra ZT421 is built for businesses that print labels every day and need a machine that gets on with the job without constant attention. At 300 dpi (12 dots/mm), barcodes and text stay sharp even on small labels — no squinting, no scanner misreads. And at 305 mm/s, a batch of labels is done before you have time to think about it.
Peeler and rewinder built in
The built-in peeler lifts each label off the backing paper automatically, so your team can apply them in one smooth motion without fumbling. The full-roll rewinder collects the used backing neatly on a spool — the floor stays clear and the workflow keeps moving without anyone stopping to tidy up.
Colour touchscreen and real-time clock
Changing settings takes seconds on the colour touchscreen, directly on the printer, without opening a laptop or calling someone over. The real-time clock (RTC) logs the exact time of each print job, which is genuinely useful if you need to track when labels were applied in a stockroom or production area.
Connects to what you already have
The ZT421 comes with two USB ports, RS232, Bluetooth, and Ethernet on board. That covers the vast majority of point-of-sale systems and ERP setups without adapters or workarounds. ZPL and ZPLII emulation means most label-design applications will recognise the printer straight away — no extra drivers to hunt down.
