My father was looking for this software the other day - preferably free as he only had one job to do.
He gave up. The only free one he found was SimpleOCR 3 which he said wasn't much better than the OCR program he had in the 1990's.
He came here this morning and used my Omnipage Pro.
Beware if you Google SimpleOCR - SiteAdvisor comes up with a lot of danger signals.
