finereader is THE best OCR s/w ever...no competition whatsoever.....it even scans and converts tables as is in word documents and excel sheets..try scanning a newspaper clipping and u'll find that finereader even creates frames and adjusts the words....its a must try...
btw.....all u need for the OCR s/w to work properly is to install the scanner s/w and driver....the OCR s/w will automatically detect it and use it to scan...
