Digital BW, The Print

As Ed explained it - and I'm no expert on the math or mechanics - the  res
of the 1680 is 1600x3200. A full optical resolution is 1600, but you can go
to 3200 and only have data interpolated in the X axis of the scanner head
travel. Again - I think... Suffice it to say that at prints up to 12x12" I
can't see any difference between 1600 and 3200.
