There's an old thread on geekhack discussing dyesub keycaps. There's also a Japanese guy making them.
But now much news after that.
I'm just wondering, how is the state of dyesub printers nowadays? I need to buy a color printer recently, and am looking at a bunch of options. But if I can buy a dyesub printer and use that to print keycaps and paper alike... or am I still dreaming?
