I have a requirement that PDF’s I generate are valid up to a particular date. After that date the PDF should not be printed or even viewed. Is there a way to do this?

This feature is not supported and I don't think we can support it. I have never heard PDF protection based on date. If you kown anything about such technology please let us know.
