There are really a lot of options for this. Before Office or Corel had built-in features or plug-ins, there was the ubiquitous "PDF printer." I've been using the freebie version of PrimoPDF since what must be 2003 ("paid" is "NitroPDF"). And the freebie keeps asking me if I want to "streamline" my installation, and I always click "No."
I think Intuit Quicken has a PDF printer, as do some other applications.
If the notion of "printer" is confusing, these softwares will allow you to save a PDF file of "image" specification to your computer document archive.
However, we would all want to have "searchable" PDF. There are applications which provide for converting an "image" PDF to a searchable. Maybe if you get lucky looking for shareware, you could find something. But you more likely will pay for it. NUANCE software has features built-in for PaperPort 14. NUANCE PDF Converter will also do it for you. If you use OCR software (like -- again -- NUANCE OmniPage), it will most obviously provide for simply saving a scanned result or image PDF conversion to file as searchable.
AFTERTHOUGHT: I've tried NitroPDF, and it probably has the searchable-conversion option -- see for yourselves. It seemed pretty good. But I've chosen a lot of document manipulation software, and prefer a smorgasbord approach.
For instance, I haven't used Adobe Reader for years. I prefer PDF Xchange Viewer or "Editor-Lite" because I can add annotations, circles and arrow, boxes and lines to my heart's content. These can be either for my own edification (old tax documents) or for transmittal elsewhere (a "form" editor for quick and dirty PDF image scans). Xchange allows you to re-print the result of this feature as another PDF -- slightly grainier in its appearance than the virgin original, but really more than adequate. That is, you can save it as a file with the original annotations and print it to paper that way, but you wouldn't want to transmit your personal signature as a graphic object in a PDF readable with shareware. So you merge everything as an image PDF.
ONE MORE: As much as NUANCE is a specialty software-house producing very sophisticated products for OCR, document archive database and voice-recognition with AI training, I still want to say "Screw them! For their aggressive marketing technique through the Update Manager also deployed by Roxio -- and screw them again. But it is able to DIS-able, no less than easy to DIS the software firms.
