The 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 the ATM machines, lockers, POS and supermarket electronic scales in the life. The printer uses a 5~9V wide voltage supply mode. The higher the voltage, the clearer the printing effect. It is suitable for thermal paper rolls with a width of 58MM and able to provide a print life of 50 kilometers. 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. Combining with various sensors, we can DIY all kinds of practical instruments such as electronic scale, blood pressure index measuring instrument, soil element analyzer and driving recorder. Besides, we can also make a small ticket printer of our own. The content on the small ticket can be defined by ourselves. After further development, we can even realize the remote printing function.

Embedded Thermal Printer - TTL Serial Communication Interface
Note:
- 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.

Jargon buster
Plain-language definitions for the technical terms used above.
- ESC
- An ESC, or electronic speed controller, is a driver commonly used to control brushless motors, especially in drones and RC vehicles. Comparing this board with a conventional ESC matters because FOC drivers can offer smoother low-speed control and more precise torque or position control.
- IDE
- Short for Integrated Development Environment, a program used to write, run and manage code. It matters because some learners prefer a traditional coding workspace instead of a guided notebook-style lesson.
- TTL serial
- A simple serial data connection that uses microcontroller logic-level signals rather than computer RS-232 voltage levels. It matters because the camera can connect directly to many microcontroller pins or a USB-to-TTL serial adapter, but not safely to an old-style RS-232 port without conversion.
