I bought a laser cutting machine, put it on low, and just burn the text onto the paper. No cartridges to return or refill ever. I currently use solar panels for power, but I don't like the 80% inefficiency, so I am looking into using a lens and fiberoptics to use the light directly. This way I can also incorporate a prism and do color printing.
