Yes. Most thermal printers have a single printhead, so to print in colour, you simply replace the black ribbon with a coloured one. However, process colour printers—which can print multiple colours and a black barcode in one pass—are available, though they are more expensive than standard desktop units.
For barcodes, always use a black or dark ribbon to ensure readability.
There’s a limited range of coloured ribbons available for most thermal printers, and we’re happy to help you choose the best option for your label material and application—just ask!
