Hi,

Following the man page of cupsd.conf, your asumption might be wrong:

man cupsd.conf
...
       Encryption IfRequested

       Encryption Never

       Encryption Required
            Specifies the level of encryption that is required for a
            particular location.  The default value is "IfRequested".
...

But you're correct in the sense that this is only valid Within Location
And Limit Sections.

Thanks for your feedback anyway.
