[sane-devel] Which scanner for doing good OCR under Linux ?

I suspect that pretty much any scanner will work for this purpose.
OCR usually works best with monochrome or grayscale data, so any
scanner that can scan in these modes with e.g. 300dpi will work.

I only have first-hand experience with EPSON scanners and OCR, and
all I can say is that the scanner is not the limiting factor: It's
usually the OCR software that limits the quality of the OCR process.
The same image OCR'ed with different software packages gives totally
different results. Unfortunately I have not yet found an OCR
package for Linux that I consider "good enough". I've had very
good results with Abby FineReader on a Mac and with Windows.
