Great summary. I agree.

Agreed; which, I presume, is why Roger K deBry [RKD] suggested that
only 'publicly available' [a question-begging term, IMHO] documents
could be printed by reference:

My answer is to say that no credentials of the user are employed by
the printer to obtain the referenced document; instead, whatever
credentials of its own the printer has are used. This degenerates
to Rogers' model when the printer has no credentials of any kind
(but note that the document repository might choose to consider the
source IP address or domain name of the printer to be a form of weak
but acceptable credential). You might need an extra status or two
to communicate the inability of the printer to access the referenced
document, but I suspect you need that no matter how you do this.
