Thermal Printer Module (5-9V, 3A, TTL)

This thermal printer module can be used in a wide variety of scenarios such as receipt printing, parking tickets, bus & taxi tickets and meter print outs. It can also be used when making your own PCBs by printing on thermal transfer paper! It supports Arduino, Raspberry Pi, and Windows System. We can refer to the instruction set and use the USB serial port or TTL communication interface to send corresponding commands to the thermal printer. Then the printer will instantly print out the text, characters, barcode, QR code and even black and white pictures according to the instructions; we can connect it to the Arduino controller or the Raspberry Pi by a serial port. The higher voltage of the embedded thermal printer, the faster printing speed, and the clearer handwriting of the printed documents (voltage range is 5~9V). At the same time, the normal operating current is between 0.8A and 1.5A. The instantaneous current can reach up to 2A. If the weather is cold, the operating current will need to be increased accordingly. The power consumption for printing graphics is generally large. If the printing ticket involves graphics, it is recommended to select the appropriate power supply. To print characters like Chinese with Arduino, you need to create a C file, and it cannot be compiled under Arduino IDE (Chinese character cannot be input under the IDE development environment. The printout will be garbled even if you use the clipboard to paste these characters into input end). Then write the relevant array data into C file for calling. USB interface supports computer system such as XP, win7, win8, and you need to install the driver on them before you can use it.
