Hello,
I use the \pdfinfo primitive to manage meta datas in pdf files when I use pdflatex.
However, I'd like to manage :
-printing option : authorized or not
-pages extracting : authorized or not
-protection...
How can I do this ?
I heard that it was possible to do this with old versions of pdftex but these kinds of features were removed from it because it didn't work very well.
I would like to know if these features will appear again and, why not, in LuaTeX ?
optimizations are best done after the document is created and not on the fly (ghostscript can do it)
the code was removed because it was too much interwoven an unmaintainable; also, such features have to be under complete user control if only because other features (\pdfobj etc) might demand such control; when the luatex backend code is redone (2009/2010)we might provide hooks for users (macro packages) to implement such features

Yes it would be cool to allow packages like hyperref for example (or others) to set printing options ... Thank you for answering fast. Jack
