I just got done trying this and it didnt work well at all. I taped
the edges of the foil to regular paper and ran it through the laser
printer. I printed on the dull side of the "release" foil. I think
the dull side is the one with the magic coating. Anyway my traces
are missing spots and have what looks like bubbles throughout.
Is this the kind of results others are having?
