Restrict print copies on a PDF
- by Chops
We have a very specific use case for an application we're developing, where a user will be presented with a PDF document, which they can print off. However, we need to be able to restrict the PDF so it can only be printed off once. Does anyone know if there's a way to restrict the number of times a PDF can be printed.
I'm aware the PDF spec has lots of security features, but I've not found reference to anything like this before.
Many thank.
