   Can I expire a pdf after a certain date with encryption method or can we limit the number of print for a pdf file? Suppose only 5 prints are allowed.

	You can add a custom field (similar to meta data fields). There you can modify a value after each printout. Before printout you can check this value. How to set the security settings from inside the pdf i don't know. For this all you need embedded javascript-code. The other thing: The users can stop javascript executed from the pdf-reader as a security option. No good news for you. For my opinion there isn't any save solution for your needs. Cheers, Ingo

	or Encrypt the pdf file (password for open and password for changes and only your program knows it). You write a program that will be opened, printed, and save / check somewhere (registry?, database?) number of times the file was printed. Regards
