The advantages of thermal printers compared to other printing technologies are their cost and maintenance-free operation. Thermal printers are quieter than inkjet or laser printers, as they do not require additional air pressure or cycle mechanisms to print. In addition, they use thermally activated paper that is heat sensitive instead of using inks, toners or ribbons, thereby saving on consumable costs. Thermal printers also have higher print speeds than most other types of printers, making them ideal for high-volume environments. However, thermal printers also have some disadvantages including the limited lifespan of their printheads – they are estimated to last 1-3 million prints, after which they need to be replaced or serviced – and their low-resolution levels. In addition, thermal papers tend to discolor over time, and documents printed on this type of paper may curl up when exposed to moisture, increasing the chances of smudging or fading. Finally, some specialized applications such as desktop publishing may require higher resolution prints and more complex colours than what can be achieved with a thermal printer.

How does a thermal printer create prints?

A thermal printer works by using heat to transfer a design or text onto paper. Inside the printer is a printhead containing small dots of thermal material, similar to wax-based ink. When a design is sent to the printer, it passes through the printhead and electrically heats up each dot. As the dots heat up, the thermal material is transferred onto the paper in the form of a design or text. The heated dots are retained on the paper, creating a long-lasting impression that will not fade or smudge like other traditional forms of printing. This makes thermal printers ideal for applications such as shipping labels and receipts that need to retain their legibility over time.
