Introduction The Thermal Printer Mechanism for Citizen Printer do not involve ink cartridges or carbon tapes. Secondly, our products are very easy to use, so the buttons and software involved are used less. Finally, our products have the advantage of low price but long service life. Feature The greatest advantage of our products is that they are easy to load paper. Secondly, The Thermal Printer Mechanism for Citizen Printer are also characterized by small size and light weight. More importantly, our printing speed is very fast, and the machine does not produce loud sound during work, and finally, our product life is also very long.
