Product FAQs

What’s the difference between thermal transfer and direct thermal printing?
Thermal transfer printing uses a ribbon to apply ink onto the label, ideal for durable and long-lasting labels. Direct thermal printing uses heat-sensitive paper and requires no ink, making it ideal for short-term labels.

How wide can I print labels?
The Zebra ZD421T can print labels up to 108mm wide, perfect for a variety of label sizes.

What comes in the box?
The pack includes 1 Zebra ZD421T Thermal Label Printer, empty ribbon take-up cores (1 in. and 0.5 in.), 2 x 300 m ribbon core adapters for non-Zebra ribbon, AC power supply, power cords, USB cable, and guides to help you get started.

RAJA offers a wide range of labelling and printing solutions, ensuring your workplace is equipped with the tools it needs to stay organised and efficient.

Our product advice

Thermal transfer printing transfers both black or coloured inks onto the label using a resin or wax-based ribbon. Labels and ribbons are both required to print.

Direct thermal printing uses specialised thermal label paper but does not need ink.
