I have posted multiple times in the past about using Tracker Software's PDF XChange Viewer not as a PDF reader, as it's accessibility is "iffy" for that purpose, but as an OCR processor for PDF files.   Here's the tutorial: Using Tracker Software’s PDF-Xchange Viewer to OCR Process Image Scanned PDFs

I have yet to have anyone say that the resulting OCR processed file, once saved, didn't read just fine in whatever their preferred PDF reader program was.  It has the added bonus of having a full set of non-English OCR options.  If memory serves the software handles English, Spanish, and German as shipped, but I had a client who was using it with the Swedish OCR language pack they offer (also at no cost).

Constantly insisting on “my rights” with no consideration of “my responsibilities” isn’t “freedom” — it’s adolescence.
