I tried a crude test that didn't work out too well so I can tell ya one
way that wont do it :)
I used 'slug tape' its an adhesive backed copper foil the critters don't
like to crawl over and stuck a strip of it down on a sheet of paper thinking
I could laser print the traces directly and etch , I would have used overhead
transparency film for the backing if it worked
unfortunately the toner doesn't stick well to the copper so it would get
layed down in the right place then either stick to the hot roller and get
redeposited further down the page or just barely stick to the copper
and peal off once it came out
it might have worked better if I had roughed up the copper surface a bit
but I had a feeling it wasnt going to do that much better
it was worth a shot anyway ,maybe if you used a photo resist instead?
