Introduction

An Arduino library for the Adafruit Thermal Printer:

These printers use TTL serial to communicate. One pin (5V or 3.3V) is required to issue data to the printer. A second pin can OPTIONALLY be used to poll the paper status, but not all printers support this, and the output on this pin is 5V which may be damaging to some MCUs.

Adafruit invests time and resources providing this open source code. Please support Adafruit and open-source hardware by purchasing products from Adafruit!
