It seems that Straighten or Deskew would be a pretty basic option in scanner
software (as opposed to image editor).

For a long time, I thought that my Epson 4870 scan software did not support
deskewing in Professional Mode ... which was a mystery, since I saw it
implemented in Full Auto mode. Finally I figured out that the image will be
deskewed if you use Thumbnail Preview as opposed to Normal Preview. The
problem with that is, the deskewed thumbnail preview is too small, appears
in a big "frame", and the "Full Size" button to view a larger version of the
Preview is grayed out!

The thumnbail preview looks like this:

See the big frame? Has anyone found a way to get a bigger deskewed preview
to work with?

I tried the bundled Lasersoft Silverfast SE software ... I upgraded to the
latest version 6.4.3r8 ... looked at documentation, and Lasersoft forums ...
it appears that the software has no deskew / straighten function whatsoever!

Any other hints on how to get a decent sized deskewed preview with my Epson
4870?

Is there other scanner software implement deskewing better?

I wouldn't even try to deskew with teh scanner software - and wish it were
easy to disable with my (old) HP 3300C scanner. Deskewing needs some sort
of resampling of the image; the scanner software's resampling algorithm is
likely not to be all that sophisticated - you're probably better off not
deskewing at all in teh scanner, and then loading the image in an image
editor like PhotoShop (Elements) or Paint Shop Pro. I certainly got
significantly sharper results with that approach.

Buy Art-Copy Business from ScanHelp.com It, unlike your other options
given so far, will deskew while scanning. So you will be able to scan
it, and not have to open it to edit it.
