The Zebra QLn420 mobile label and receipt printer is an optimised QLn series printer that can tackle heavy-duty applications of four-inch label and receipt printing. Designed and constructed to withstand the rigours of printing on-the-go, this model has a clear and simple user display, and uses Zebra Link-OS and Multiplatform Software Development Kit for easy integration, management and maintenance. The Zebra QLn420 can also handle heavy-duty print cycles for eight hour stretches thanks to its removable, rechargeable PowerPrecision+ Lithium-Ion battery with built-in battery charger. 

The Zebra QLn420 is being replaced by the Zebra ZQ630. We are expecting a final re-stock in June and Zebra will be offering servicing and engineering support until 31st December 2025. There may still be a few QLn models in stock, we would be happy to check availability for you. If you need support or more information to transition over to the Zebra ZQ630 please let us know.
