I was addressing this scenario in my previous e-mail today,
The job-id will be an operation attribute, so job addressing within a
printer should be
taken care of.
To address the printer, we would have to decide on one of two rules :
1) * the entity processing the request is representing only one printer and
no additional attribute is necessary
2) * or as Tom mentions above, printer-name should assist in addressing the
target
2) seems more flexible.
