Since I dont have the proper american words for some items, I'll try to 
explain instead. Yes, it works!  The easiest way would be to find 
paper, coated with that glue that gets sticky with moist, like licking 
on a stamp or closing an envelope. But since I couldn't find anywere to 
buy it, i make my own, by coating matte photo paper for inkjets with 
Gum arabique. That glue does not melt from the heat, but dissolve 
easily in water, leaving the toner on the copper without any rubbing.
The problem I'm working on now is to get a smooth surface when coating, 
rubber scrape (for window cleaning) seems as a way to go.
