Embedded Thermal Printer - TTL Serial Category_Grove (Arduino)/Grove Radio/RF a 32GB microSD cardThe embedded thermal printer uses thermal technology, it doesn't need to add toner or ink, stable performance, and mini size. The embedded thermal printers are widely used in instrumentation, food inspection, shopping terminals, and other scenarios. It can be found in ATM machines, lockers, POS, and supermarket electronic scales in life. The printer uses a 5~9V wide voltage supply mode. The higher the voltage, the clearer the printing effect.
