Hello friends!
I have an interesting project that I'm trying to finish. My project is associated with an attempt to print an image on a thermal printer by Arduino.
I connected the printer to the Arduino board, wrote my sketch and brought to print easy image. Its just line or pionts. But when I decided to print text or an image, it did not work out.
Please tell me how can I fix my sketch for printing text or images on the Arduino?
