4. I want disallow to print the pages with the print function (I know with print screen you still can print it.)
No way.
No way with pdftk? Because this is a feature of PDF files that Adobe Reader respects. Whether other PDF viewers do as well or whether there's some magical way the PDF file can prevent printing without the cooperation of the viewing application, I don't know, but it's definitely a feature of the current PDF spec. In Adobe Reader when you open a document with any of a variety of these restrictions (or add-ons such as high-resolution color printing instructions or other attachments), Reader will notify the users of any such special status the document bears.
