Thermal printer isn't Printing Images
I am using a 2 inch thermal printer with arduino uno r3. I used adafruit library for thermal printer i.e. "Adafruit_Thermal.h". With this library the text (Strings) are printing fine, but when there comes a bitmap image, the printer just prints some garbage dots.I made only one change in Adafruit_Thermal.cpp which is baudrate. My printer's baudrate is 115200. The printed output image is attached. Please guide me how to fix it.
