Thought I'd resurrect this topic from a couple years ago to see if anything has changed.
I'd like to restrict printing of a PDF coupon to one or perhaps a defined number of copies once a user has the PDF downloaded.
There is one company that sells a program to do this (Safeguard) but they have priced it ridiculously.
There is an online subscription service (FileOpen Systems) that circumvents having the PDF downloaded so that the user can only print a defined number (might be the best solution), but was hoping Adobe either may have added this feature or a simple plugin exists to do this.
