It appears as if this thread is the beginnings of yet another print =
protocol. I would argue in favor of using existing protocols "TIPSI or =
even SNMP," as suggested by Don or at least leverage their strengths. I =
believe the protocol could be the same between client and server and =
client and printer. IPP is a simple solution for Internet job submission =
but it doesn't address the complexities of printer management that TIPSI =
or SNMP do. Is it the objective of the PWG to grow IPP to include printer =
management capabilities like TIPSI or SNMP and richer job control like =
DPA? I would hope that over time there would be a convergence of =
protocols that meets the needs of embedded devices as well as the need of =
hosts to servers, perhaps in a single protocol.

I think Roger (correct if I'm wrong, Roger) meant that IPP, as currently
defined, is the correct solution for server-to-printer protocol, IF the
printer device already has an embedded web server, like would probably
be used for overall management. And if this is the assertion, then I
tend to agree with it, although it depends on what the exact
*requirements* are for server-to-printer protocol.

I can easily agree with Roger on #1 and #2. I think where
the problem lies is with #3. I am not sure how broad the
definition of "imbedded server" is? Does that mean imbedded
IPP server or any server? All of my network printers today
have available what we call an Internal Print Server which
supports a wide range of protocols. Is that what you mean
Roger? I don't think so. I think the definition needs to
be "imbedded, spooling print server." And even then, I think
we have lost a huge amount of control and status information
that is available from TIPSI or even SNMP. Maybe we need
to define some kind of passthrough for IPP that allows
the control and status information for the down and dirty
hardware to be retrieved and set through IPP??
