How Thermal Labels Work
Thermal labels operate based on a simple yet effective principle. The label material, typically paper or a special film, is coated with a heat - sensitive layer. When a thermal printer's print head applies heat, the heat - sensitive coating undergoes a chemical reaction, changing color and creating the printed image or text. This process is instantaneous, allowing for quick and efficient label printing. For example, in a busy supermarket checkout line, the thermal printer can rapidly print price labels or product information labels as items are scanned.
