It's a known problem with the 5p. Unlike all other ScanJets, the 5p
doesn't support the commands that specify the scan area in decipoints.
Instead, it only supports the commands that use the device-pixel unit.
So the HP backend needs to be changed to use the device-pixel commands
(all ScanJet scanners support this). It's not hard to do, but since I
don't have an HP scanner myself (yet), I can't do this effectively.
If you want to give a shot at it, let me know (I have the docs for the
necessary commands).
