Re: PDF is blocked for printing, etc. OK for acroread (it behaves as expected), but KPDF allows me to print it, even if it is protected! Why?

I was not able to do it, because of `human' and organizational reasons.
I had no choice!

To maintain honesty? An honest soul (i.e. me, here) has to send some
data to some dishonest person.

I know, and we all know this. But this needs some determination, because
it needs some time. And when such problems arise, one often thinks (or
should, at least, think) `Do I really need to copy this using that
painful way, to bypass some limitation which is actually imposed to me
by an honest person?' This is another aspect of security. There are the
technical means, and all the infringements which can be done. But,
sometimes, `le jeu n'en vaut pas la chandelle.'
