oh yeah. thermoform paper. the problem is that any heat tended to permanently deform it. it did produce some nice sharp braille.
I am not material expert but i think it is possible to make thermoform "paper" that could be thermoformed multiple times. once when printing then ironing out. Even if it would be expensive - just use few meter strip running in a loop! no waste of material, elegant and USEFUL tty-style work under unix for blind person.
at least 10 times more productive than "screen readers". And no voice produced.
the same printer - with an option to put cheaper single use paper - could be ued to make braille printouts.
While unix style computing is far more efficient than any "modern" style, with blind person the difference is simply enormous.
