How Direct Thermal Technology Works
Direct thermal printing uses a heat-sensitive paper coating. As the label moves under the printer's thermal printhead, microscopic heating elements selectively activate the black micro-pigment chemicals in the paper, instant-forming your shipping address, barcode, or text without liquid ink.
Key Benefits for Ecommerce & Dispatch
Because direct thermal printers have no ink cartridges, printhead ribbons, or laser toner drums to replace, they offer lower operational costs, zero smudge drying time, and ultra-high reliability during heavy order dispatch runs.
Direct Thermal vs Thermal Transfer
Direct Thermal paper prints directly using heat and is ideal for shipping labels, receipts, and courier tags with a 1-2 year lifespan. Thermal Transfer uses a wax or resin ribbon to melt ink onto synthetic material for long-term outdoor or chemical exposure.
Key Takeaways
- Direct thermal labels require zero ink cartridges or printer ribbons.
- 100x150mm (4x6") is the UK standard courier shipping label size.
- Standard desktop printers use 25mm (1 inch) cardboard roll cores.
