Demo Code for the (CSN-A2-T) thermal printer available from SparkFun Electronics. Simply connect to a serial UART with a sufficient power supply to print on thermal printer paper!
- Installing an Arduino Library Guide - Basic information on how to install an Arduino library.
- /Firmware - Example Arduino sketch to run the printer
- /QRprint - A library and example Arduino sketch for generating and printing QR codes.
All other code is open source so please feel free to do anything you want with it; you buy me a beer if you use this and we meet someday (Beerware license).
Thanks to Chris Wheeler for the Arduino 1.0+ compatibility update!
