I want the user to view a PDF file without being able to save (<kbd>Ctrl</kbd>+<kbd>S</kbd>) or print (<kbd>Ctrl</kbd>+<kbd>P</kbd>) the document. The user should neither be able to copy the text inside the PDF. Is is possible?

In terms of not wanting to allow the user to download the PDF - which if you send the PDF as-is to the browser and it opens it inline most browsers offer a download option -- then you should look into rendering the PDF using Javascript.
