I don't know about the ScanSnap specifically, but I suspect that
1200dpi mode may be interpolated, not true optical 1200. In either

any scanner I've used (my main workhorse now being a Fujitsu
fi-5750C).
It's like the difference between laser printing and real typesetting.
'course many people can't see the difference.
Below 2400dpi, the characters in the text are not as smooth.
Even 300DPI scans of 300DPI are unlikely to be lined up, to keep from
getting degradation.
