I wonder if the wet-paper printer that you remember used a similar process to the one that my folks' liquid toner photocopier did back in the 80s? It used an electrostatic toner adhesion process followed by a fuser. Just like contemporary laser printers and photocopiers, but with the toner particles suspended in a liquid carrier. The volatile carrier smelled awful, and the finished copies had a fingernails-on-chalkboard like gritty feel in the hands. I seem to recall that it needed specially prepared paper.
