There were always dreamers so:

There was a Canon inkjet that had a fluid in one of the heads to
make the paper more inkjet compatible or something like that.
There was a HP inkjet with a heated wire just after the print
area to dry the ink fast.
There's the First foil that is heat treated with infrared after
printing to enclose the pigment ink in a resin.
