Direct Thermal Printing Notes

The Zebra ZD421 direct thermal printer uses heat-sensitive label media and does not require a ribbon. This makes it a practical choice for barcode labels, inventory labels, shelf labels, healthcare labels, shipping labels, and other short-term labeling applications where direct thermal media is appropriate.

If your labels need to withstand long-term storage, outdoor exposure, chemicals, abrasion, moisture, or heat, a thermal transfer printer may be a better fit. Spartan POS can help you choose the right Zebra printer and label media for your application.
