A thermal roll is a specialty paper roll with a heat-sensitive chemical coating, used in thermal printers for inkless, quiet, high-definition printing in POS systems, ATMs, and receipts, where heat from the printhead activates the coating to create text and images, offering an efficient, cost-effective solution for fast-paced environments like retail and hospitality.
Key Features & How it Works:
Chemical Coating: The paper has a top layer of dyes and developers that change color when heated, creating an image.
Inkless Printing: No ribbons or toner are needed; the heat from the printer's thermal head triggers the chemical reaction directly on the paper.
Heat Activation: A thermal printhead applies heat, causing the coating to turn dark (usually black) to form text and barcodes.
Quiet Operation: Thermal printing is significantly quieter than impact printers, making it ideal for busy settings.
Varied Sizes: Available in different widths (e.g., 55mm, 79mm) and lengths to fit various devices.
Common Uses:
Point-of-Sale (POS): Receipts for retail, groceries, and restaurants.
