There is no pre-defined gpo settings for any of the above.
Also I am sure admins in an enterprise settings don't take cynicism.
I've been through that documentation, this isn't the first time I am trying to accomplish this. However it seems awful that there is no way to set adobe printer preferences via a gpo, it also doesn't make sense that you cannot set security settings via gpo. There are other much cheaper pdf printer solutions that specialise in managing the pdf printer and adobe does not.
I do not believe that the password is only set in the document, otherwise how does the printer use the 'Use last known security settings' for it's secrutiy option?
