You can accomplish PDF encryption with pdftk (for example): http://www.pdflabs.com/tools/pdftk-the-pdf-toolkit/ You use that to restrict certain features (in your case printing) and protect that restriction with a password. The PDF itself can still be read without password. Of course the PDF viewer has to honor that restriction. If the user finds a PDF viewer that doesn't give a **** about these restrictions, they can still print it. But I think that doesn't really matter for your scenario anyway. :-) --=20 Best Regards, Andreas ------------1151E40CD088BC098 Content-Type: application/pgp-signature -----BEGIN PGP MESSAGE----- Version: GnuPG v2.0.17 (MingW32) iF4EAREIAAYFAk+jsyQACgkQIxziJkiYZxH0NgD8DgNsyCWl1CQIGxHCnYMAnFw0 jKrgUOTL77AqGHPy+h8A/jceO6syp7jfl+TGwFzAIZxtNoKhSgutJINilO3VlRlf =PPEA -----END PGP MESSAGE----- ------------1151E40CD088BC098-- --===============0781960381== Content-Type: text/plain; charset="us-ascii" MIME-Version: 1.0 Content-Transfer-Encoding: 7bit Content-Disposition: inline ___________________________________________________________________________________ If your question is of interest to others as well, please add an entry to the Wiki! maillist : ntg-context@ntg.nl / http://www.ntg.nl/mailman/listinfo/ntg-context webpage : http://www.pragma-ade.nl / http://tex.aanhet.net archive : http://foundry.supelec.fr/projects/contextrev/ wiki : http://contextgarden.net ___________________________________________________________________________________ --===============0781960381==--
