Homebrew PCBs

you CAN print directly to pcb (strip down a printer to take straight 
through feed) but you are going to have to find an ink that is water 
proof and will not clog up your print heads (this is the big catch).
 I have printed directly to pcbs but it was with the standard ink in 
the cartradge--but it is not resist proof. it prints out a great 
picture but resist and water washes it off.
if you can find some ink that works you will have found the holy 
grail.
