How to disable print screen using Acrobat 8 Security.

I don't think it's possible.

I know you can disable print screen some web files, but it'll be possible through other utilities.

As far as I know you can't disable print-screen in Acrobat easily. Print-screen functionality is handled by the OS and Acrobat does not seem to have control over it. In any case, you can't stop the determined - even if you stop print-screen, people will still be able to take a photo of the screen using a camera ;-)

You can't set a limit on the number of times the document can be opened using desktop Acrobat products. It is possible using Acrobat's server infrastructure, however this is quite complex and expensive.

Unfortunately there is no quick and easy way to achieve what you are proposing.

Also you can rip the security off a PDF document relatively easily.

It will only stop the honest people.

Wow, What digital delivery methods do most people use who have an ebook or tutorial? What are the options out there?

Thank you for the great ideas to put a watermark or copyright my material.

You are not able to stop screen capturing, you may stop the windows built in function with various utilities but there are a lot more ways to do a screen capture.
