Your right, I didn't mean to accentuate the word so as to mean an exact
doubling, just that the effect was indeed visible. If anyone is curious to
see the effect just make two black squares in PS and get them to partially
overlap.

Like I say, it's probably not worth the extra work for most images, but it's
worth keeping in one's bag of tricks.

Hmm, My guess is that if the driver were doing it on-the-fly you might get
ink bleed / dot gain, which would sacrifice detail, but with some dry time
between applications the paper holds the ink better?
