Omnipage and other OCR packages have a virtual printer application that
allows the software to create a TIFF of the PDF file and then OCR it.
However if the flag to prevent printing is thrown then this route of access
is also blocked.

This article is very very good indeed. It aught to be read not simply
because of the details it gives to the inner workings of PDFs, but also the
context including colaboration of Adobe with outsiders in the access
technology world, as well as screen reader developers.
One or two questions could be asked here on list arising from this article.
1. With reference to PDFs which contain only scanned images of documents,
how do people go about extracting useful readable text from these? I know
it is possible.
2. Does anyone know of tutorials, as well as reference material, for
helping people to use Acrobat Reader more effectively?
We have all from time to time come across PDFs which are simply not
accessable through them being image only documents, or just poorly produced
and not marked up. In fact the latter, accessible markup, is rarely done in
my experience. Is it just laziness on the part of media boys and girls, or
more likely economics; no one can spare the time to actually do it?
One thing I have always been certain of is that Adobe has certainly done a
lot, for whatever reason, to make this, originally, unaccessable format
usable by us. Certainly, as always, there's room for improvement, i.e. a
message when the page processing has finished? One thing is certain:
people should not so freely criticise Adobe and the PDF format, not without
reading this article first! AS the great man said, "Don't criticise what
you don't understand."
Just like the work being done in web development - CSS, XHTML, and maybe,
eventually, SVG, a standard that serves all is definetly the way to go, not
a perpetual craving for the old standards, and separate documents and
sperate wbsites for the poor blind.
And here is the link to the article again.
