If you have a scan-2-text converter rather than simply a raster reader.

You can do this without Ghostscript.  I've taken the output of
various text processors and reconstructed an ASCII version using
perl (this is also doable in awk).  You need to search for the (x,y)
coordinate settings, and translate these into row and column positions,
and then "drop" the strings enclosed in parenthesis at that position.

Hard things are if the postscript contains reverse line motion
(which requires you to buffer a whole page).  Or, if the point sizes
vary a lot. Of course, this approach won't handle graphics and other
stuff, but as long as your scanner is reasonably accurate in only
snagging x:y and text display commands, it'll work well enough.

If you're familiar with awk or perl, you can usually whomp one of these
things up in about an hour.  Sorry I didn't save the one I did for someone
else on the net.
