In this tutorial, we will interface a thermal printer CSN A1 with widely used PIC microcontroller PIC16F877A. Here in this project, a thermal printer is connected across PIC16F877A and a tactile switch is used to start the printing. A notification LED is also used to notify the printing status. It will glow only when the printing activity is going on.
