Without quoting all of it, I agree completely with Larrys suggestion
to formulate print-by-reference to allow including 'transferable'
credentials (there are security schemes out there that include such
things). If there are no credentials supplied, the request
degenerates to my suggestion that the printer provide credentials of
its own, etc...
