indeed. the reason is magazine, or most form of bulk printing use dyes,
which are soaked-up by paper and work by staining the cellulose.
laser toner OTOH has tiny particles of plastic, which actually "sticks" to
the paper surface, and is neither soaked-up by paper, nor stains it.
the transfer of toner (from magazine / glossy paper, to copper surface)
happens due to 2 reasons --
1) gravity - the hot molten plastic falls from paper on copper, and sticks
to copper. which is why transfer works best when paper is on top of copper,
with heat being applied top-down, and not the other way around.
2) higher adhesion of plastic to copper (or other metal), than paper
