We're live on the modules page! Thermal Printer.
Sorry that took so long.
As far as ASCII art: huh, must have been someone else? I was talking to someone who wanted to hook up a thermal printer to Tessel to make a photobooth that would take your picture with the Tessel camera, ping an API to turn it into a portrait in ASCII, and print it out for you. I still think that's a great idea/would be such a good demo
Thanks for making this cool module!
