This is the Adafruit thermal printer, whose Arduino library is published here: http://www.ladyada.net/products/thermalprinter/. This is a basic port to mbed that needs proper testing. The first printBitmap function is implemented but not fully tested, the stream versions are not ported yet.

Dependents:   SMS_LEDMatrixPrinter
