Toner transfers directly to pcb stock very easily, and very fine
traces can be achieved. The problems are more mechanical than
electrostatic. I, and several other people on this list have done
this over and over, using a variety of printers and mods. It's also
much easier to implement than either toner transfer or inkjet printing.
