Disabling copy/paste/print in PDF is pretty weak: it only works in applications that respect the restrictions. (The PDF viewer in Ubuntu, for example, doesn't.)
That may be good enough, though: you're asking for something that's technically almost impossible to achieve.
It will probably be good enough for my customers. I expect they would consider Ubuntu to be some rare African language - I know I do! Most have trouble trying to type with more than one finger so are not really computer literate.
