     Optical Character Recognition
     OCR Product-Comparisons
     High-end and middle-level categories of optical character
     recognition (OCR) software, priced below $3,000, are now
     available, as well as traditional products that are limited to
     reading monospaced typewriter output.  At the high-end are
     'page recognition' packages, such as OmniPage and TrueScan.
     These products facilitate archiving of printed material.
