Not 100% true, but 50%.
remember? i printed on aluminum foil and 50% still transferred due to

The pickup charge is shorted, you are right.

The large ground plane would still cause trouble with that charge.

I agree! i have this epson piezo printer sitting around just waiting until
one
finds a ink. i tried staedtler red and it didn't work out.
There must be a ink!
