Ignoring signing for now...Yes, setting security to disable printing will disable the print option. The password you set is not a "password for printing" it is a control password, which controls only one thing: the ability to change security. So, yes, you are expected to change the security, save the file, then print. This is hardly convenient, but password protected printing was never an aim.
This rule does not change if you sign, except that you cannot even remove the security. So a signed unprintable document will remain unprintable forever.
1. You cannot change security settings after the document was signed because that would break the signature.
2. Same thing for e-signatures. You cannot apply them after the document is signed with a digital signature because that would break the digital signature.
2. As I said, I did not have any signatures yet...just a form with signature fields, but empty. I don't see a reason why it would prevent you from applying an image saved signature if the document has not yet been digitally signed...
Thanks for your reply. I remember getting a prompt to add the password after certain actions so that is why I thought it could be the same with the printing if the option had not been disabled.
From my point of view, I set security options for others not to be able to modify/do certain actions on my doc, but I would expect I would continue being able to do so...this way securing a document is also limiting myself as the author of the document.
Of course the inconvenience prior to signing turns into impossibility when digitally signed as you say...
I can cope with an inconvenience as I understand the way it has been thought (similar to when you protect an excel sheet or anything similar) but I also think it would be useful to find an alternative solution seeing the constraints added when the doc is signed. Printing out a document does not modify the original document...so it should be allowed (of course, in order to ascertain its validity, the printed copy would need to be checked against the digitally signed one (similar to what we need to do if we copy a document in paper...it needs to be checked against the original or even get attested).
The document may have invisible digital signatures. If it is Reader-extended then it has an invisible signature that enforces the Reader rights. It can be certified with invisible signature.
