Any good scanner these days comes with an OCR program installed on it's software cd. You could check with the manufacturer if you lost your cd.
The program is great because it can scan typed text. I wouldn't even bother much with handwritten text, though through some of the gibberish you can make out some words.
Came in handy when I had to redesign some manuals to which there were no original docs; I just scanned the printed pieces and put the docs back together again.
