Direct Thermal Printing is a printing method that uses heat to produce images on specially coated thermal paper. When the print head heats specific areas of the paper, it creates a reaction that turns those areas dark, forming text or images. This process eliminates the need for ink, toner, or ribbons. This technology is commonly used for printing labels, receipts, and barcodes. Thermal printers are often compact and efficient, making them ideal for retail environments and shipping applications. However, the printed images may fade over time, especially when exposed to heat or sunlight.
