Looks like people have answered all execept
Finally, do *any* scanners have documented interfaces?
i.e. say I find myself
a nice SCSI-connected high-speed high-resolution scanner. Am I going to be
reduced to point-and-drool with Windows 98, or can I actually hook the
scanner up to a real computer?
Some companies do allow the information out or people reverse engineer it.
I have used
http://www.mostang.com/sane/ with my scanner under Linux.
Not a huge number are supported. I have also seen a shareware one
http://www.hamrick.com/vsm.html for the film scanners but never
used it.
If you find a good solution to OCR let me know, I have looked at it
a few times and it always looks like too much work to clean up after it.
300 DPI true resolution is what I considered the minimum for an
acceptable looking scan.
