How can I make a pdf file not printable?

I would like to make my pdf solutions not printable (only readable) to help prevent circulation of the solutions between students

Using Acrobat Pro or Acrobat Standard the basic technique is to set a permission password to restrict printing, See images below:

Let's pretend you have a bullet proof "can't print" (sort of DRM it does not exist).
That does not prevent a screen capture. The applications available for screen capture provide an image that is every bit as usable as the source information that is on the screen and captured.

You'll not be able to prevent anyone getting a screen capture which can then be shared. All a rather trivial activity.

Be well...
