I use TT paper, and can do 7/7 fairly reliably. However, the limit is
my printer, not the paper - I've checked the prints under a microscope
and the toner edge just isn't "perfect" enough to go better,
regardless of the paper. OTOH it's an old drum, so it's not like I'm
trying that hard ;-)

This is on normal paper, but it gives you an idea of what I'm talking
