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. regards, --ropers
