I'd guess it was an inkjet. Isn't there a problem with laserjet
(xerographic) printing to conductive surfaces?

Why quench in cold water? Just waving the board in the air would cool
it down in a few seconds.

Well anyway, it makes some sense to me to heat up the board after
doing the toner transfer. It would drive out moisture and, I would
think, make the toner stick better to the copper.
Maybe a hot air gun would also work, although the temperature couldn't
be controlled very well. It might be OK to heat up the board well
beyond the melting point of the toner. Just don't burn the board or
damage the adhesive that sticks the copper to the board.
Thanks for this report, Randy. I've also been having problems getting
the toner to stick well to the copper, so this idea may help.
