This is an Arduino library for the Adafruit Thermal Printer. Pick one up at --> http://www.adafruit.com/products/597 These printers use TTL serial to communicate, 2 pins are required.

Full tutorial with wiring diagrams, images, etc. is available at http://www.ladyada.net/products/thermalprinter/

Before loading the example code, or even opening the Arduino software, place the Adafruit_Thermal folder in your Arduino library.

This package was modified by Przemysław Grzywacz [email protected] in order to run on Spark Core.

API changes:

• Adafruit_Printer constructor doesn't accept pin numbers anymore.
• Adafruit_Printer::begin() requires as first argument a pointer to a stream communicating with the printer. It can be for example a pointer to Serial, Serial1 or Serial2.
• Adafruit_Printer::printBitmap() fromProgMem argument is ignored, I don't know how data in program memory work in Spark Core.

I hope you find this port usefull.
