This was discussed a while ago. Several people, including myself,
tried coating paper with poor results. I recall some one claiming
that we hadn't spent enough time on it but we haven't heard from him
since. It would be really great if there was a way to do it. My
problem was that the paper wrinkled and I couldn't figure out how to
get it smooth enough to feed through a toner/fuser assembly (laser
printer or copier).
Maybe dextrin coated paper is available in bulk... The dyna-art
stuff is just too expensive, IMO.
There may be other water soluable substances that are coated on paper
suitable for laser printing. I looked around a bit with no results
but barely scratched the surface - there are a lot of paper products
out there.
