Have you actually tried this? I'm just wondering, because I have a
really hard time imagining how this could work, seeing that laser
printers tend to require and electrically charged drum, and an
electrically conductive (and potentially, somewhere, grounded) print
medium seems like it could drain the drum charge real fast, resulting
in the toner going all over the place. But maybe I'm mistaken. Maybe
the drum charge is really only required during transfer of the toner
to the drum, and maybe even the drum being in contact with a copper
plated medium wouldn't disturb the toner positioning. Maybe the toner
would transfer and get fused to the "blank PCB" just fine. Maybe. If
anyone knows, then I'd be really curious to hear.
