Thermal Printer Controller
A thermal printer is a type of printer that uses heat-sensitive paper and an electric heater to print text and graphics. Basically, it’s a normal printer but the paper it uses is heat sensitive. You cannot use normal plain papers with this as it will not print anything on it if you do so. So after knowing what it exactly is, now we move onto how does a thermal printer works? Working mechanism of Thermal Printer Controller : The working mechanism of a thermal printer has four major components: the thermal head, transfer roller, platen roller, and gear assembly. The thermal head contains two metal plates and requires no ink or ribbon because it heats up to leave an image on the paper. The paper is wound around the transfer roller and wrapped in such a way on the platen roller. When you send a print command, it will move the platen roller forward to press the thermal head against the paper over the full width of print. Finally, you see that there are gears inside this printer.
