[cctalk] OCR and line printers

[Guy Fedorkow via cctalk]

Greetings Restorers,
  I think a number of us have wanted to restore software that's only 
available as a scanned listing from a line printer.  The original 
printout probably wasn't the best typographic quality, and scanning 
doesn't improve it.
  As a first pass, OCR with tools like Adobe Acrobat can easily produce 
a rough draft of the content in text form, but it takes almost as much 
work to correct the many "typos" as it does to simply re-type the listing.
  It seems like, with all this high-tech AI processing around, it 
should be possible to take advantage of the limited character set, fixed 
fonts, and restricted grammar that one might find in a listing to 
resolve more of the ambiguities in character recognition.
  Does anyone have an approach that's more efficient than generic OCR 
and a long process of correcting typos on every line of code or comment?
  Thanks
