Could I get brief answers to the following three questions...
Do the prevent printing advanced options in Adobe Acrobat Pro X work reliably across all main browsers, such that I can safely display the .pdf files on a website, knowing that the majority of users (Chrome, Firefox. IE), will not be able to print the files, even if they save them to their local disk?
Can I go further than that and actually prevent the local saving of the .pdf files altogether?
Assuming one or both of the answers is Yes, which is what I am hoping for, will security measures prevent Google reading and indexing the files.
Actually, I want this also to be a yes. It is only the downloading and printing of the files I hope to prevent, restricting those actions to people who purchase the documents.
Many thanks in advance for your help.
