Good point about passing credentials (or lack thereof) to the printer
for print-by-reference.
What if we were to implicitly limit print-by-reference to only world-
readable documents (ie, no credentials needed)?
For the suggested scenarios of enterprise document repositories and
general public repositories (eg, IETF drafts), this should work just
fine, right? In the case of the enterprise, the repository is assumed
to be inside the firewall, anyway, so "public" access is pretty much
assumed.

The capability of being able to print-by-reference might
be thought of as similar to the capability to be able to
print any given media type. In fact, print-by-reference
might be implemented by sending, instead of
application/vnd.adobe.postscript or application/vnd.hp.pcl,
sending message/external-body.

The difficult issue in print-by-reference is how the sender
supplies the credentials if any at all are required. There
is no single standard for identity in Internet protocols, and
there's no standard encapsulation of credentials.
