I am currently working on an "input" interface to scan resposnes that I write from my typewriter and am planning on releasing a github repo on it when im done. conveniently you can type directly on the receipt printer if the response is short.

Right now all my credentials are hardcoded so i can't push out what I have without some cleanup, but I can point you to some of the libraries: python-escpos and nfcpy were what I used for the bulk of it.
