I'm not too sure where you're leading. Are supporting the addition of
the rest of the base DPA system admin operations to IPP or not?
Re SNMP over IP - of course, it runs over lots of other network
protocols. IPP on the other hand, runs on HTTP *only* and therefore
on IP *only*. It's the very fact that the Printer MIB is useful
w/ SNMP over AppleTalk and SNMP over NetWare as well as Internet
suite that makes it powerful.
As long as an asymmetric session protocol (HTTP) is used to
transport IPP, we're going to have extra problems trying
to get notifications 'in-band' for IPP. SNMP is deployed.
SMTP email is deployed. HTTP 'mini-servers' on every
desktop are NOT deployed (or likely to be).
My Vote - Add the proposed system admin operations (all from
DPA Part 3, System Admin in my copy, except 'CancelThisJob'
which may be a loose cannon as an operation) to IPP. And
do it promptly before too many proprietary alternatives
get implemented by various printer and software vendors.
