Teensy Typewriter
I have been experimenting with the Teensy 3.6 USB host library. The first result is the Teensy Typewriter project which connects a Teensy 3.6 with a USB keyboard and USB printer. Anything typed on the keyboard comes out on the printer.
Next up (maybe) an ESC POS printer command library similar to the Adafruit Thermal Printer library. The commands are not quite the same and the Adafruit library includes lots of timing specific to the Adafruit thermal printer.
After that the next project title will be "Teensy Typewriter ft. SMS". I have an Adafruit FONA somewhere. The idea is an SMS hardcopy terminal reminiscent of Telex/TWX machines.
