Acrobat Reader Notify on Print

I am creating a pdf document dynamically from php and i want the pdf document to notify the server when the document is printed. (Either before or after printing notification is fine). These are the pdf classes I found useful when trying my self. [login to view URL] [login to view URL] [login to view URL] But i struggled with the security of accrobat and could not get the development enviroment working for me. This is a backend page so we can adujst browser settings if neccessary. I would like it to work under Firefox and IE.
