Just wondering...I have a few packs of Kodak polycontrast Black and
White that probably have expired by now. Since that paper, after the
development and fixing, is designed to be soaked (washed) for quite
awhile, its properties may lend itself to toner transfer by releasing
well and keeping the image on the copper.

On the other hand, I also have some resin coated Kodak paper that is
designed not to have to go through a long wash period after fixing,
but the resin may gum up in between tracks. A third variant I have on
hand is some paper used to make B&W prints from color negatives, and
I'm pretty sure that's resin coated.

Just speculation at this point, hardly even a hypothesis. Therefore,
I think I'll charge forward and laser print some old fashioned
photographic paper tomorrow and see what happens.

Cheers,
Ted
