Perhaps not commercial books, as in novels or popular textbooks, but I've got
quite a lot of manuals produced on ancient laser printers.

I must agree here, though. Can't think of many details which wouldn't show up
in 300 dpi as well.

Agreed, but arguing that just because something is printed using equipment
with a low numeric resolution doesn't mean that it should be scanned at the
same resolution. There is no way in which the two grids would overlap
perfectly, so in order to gain every single dot, you need to scan at a higher
resolution than the source was printed at.
