What is a thermal printer and how does it work?
A thermal printer is a type of printer that uses heat to produce images on paper or other materials. It works by using a thermal head to apply heat to a special type of paper that is coated with a chemical that changes color when heated. The heat from the thermal head causes the chemical to change color, resulting in the printed image.
The process starts when the printer receives the digital data to be printed. The data is then processed and sent to the thermal head, which applies the heat to the paper. The heat is precisely controlled to produce the desired image, and the paper is then dispensed from the printer. Thermal printers are known for their speed, accuracy, and high-quality images.
What are the different types of thermal printers available?
There are several types of thermal printers available, each with its own unique characteristics and applications. Direct thermal printers, which print directly on the thermal paper, are the most common type. Thermal transfer printers, on the other hand, use a thermal transfer ribbon to print on a variety of materials, including labels and tags.
