 /*************************************************** 
  This is Docracy's sketch to use with the Adafruit Thermal Printer
  
  See this tutorial as reference --> http://www.adafruit.com/products/597
  These printers use TTL serial to communicate, 2 pins are required

  (Adafruit invests time and resources providing this open source code,
