I cast a vote with Peter. These new functions seem clearly device management
and should not confuse and clutter up IPP. Among other considerations, the
administrative authority/security to manage the device would most probably
be different than that to submit/manage jobs.

I believe that job submission and job management are clearly features in
which 
IPP is targeted for, but it seems IPP has crossed into the printer
management 
space with attributes like "Shutdown-Printer". I firmly believe that we do
no 
need Yet Another Management Protocol (YAMP). We already have SNMP, DMI, 
WBEM/CIM and embedded web, and don't need another way of performing printer 
management functions with a protocol designed for job submission and job 
management. I would therefore recommend to leave out the following
attributes 
as well as those which are not focused on job submission or job management. 
>From a security perspective, you are also opening more back doors which will

have to be dealt with.

Shutdown-Printer
Enable-Printer
Disable-Printer

Being that IPP is an IETF protocol and SNMP is THE management protocol
within 
the IETF, my bet the IETF / IESG folks would not like to see another
management 
protocol proliferate here.

We'd like to make a few more changes to the proposal.

1)  Add the "message" attribute to the request operation attribute group for
these operations:

Set-Job-Attributes
Set-Printer-Attributes
Cancel-Current-Job
Shutdown-Printer
Enable-Printer
Disable-Printer

   "message" (text(127)):
     The client OPTIONALLY supplies this attribute.  The Printer object
     OPTIONALLY supports this attribute. It is a message to the operator.
This
     "message" attribute is not the same as the "job-message-from-operator"
     attribute.  That attribute is used to report a message from the
operator to
     the end user that queries that attribute.  This "message" operation
     attribute is used to send a message from the client to the operator
along
     with the operation request.  It is an implementation decision of how or
     where to display this message to the operator (if at all).


2) Rename "Backspace-Current-Job" to "Space-Current-Job"  and add these
OPTIONAL
 request operation attributes:

"back-space" (integer(1:MAX)) the number of impressions to backspace before
continuing to print.
"forward-space" (integer(1:MAX)) the number of impressions to forward space
before continuing to print.
"non-process-run-out" (boolean) specifies whether the printer should perform
an
NPRO (move the last printed sheet to the stacker) before restarting
printing.
An NPRO makes it easier to see exactly where the spacing took place.

Remove the previously proposed "job-impressions" operation attribute for
this
operation.

3)  Add the following OPTIONAL operation attributes to the Shutdown-Printer
request:
"non-process-run-out" (boolean) specifies whether the printer should perform
an
NPRO (move the last printed sheet to the stacker) before shutting down.
"synchronize" (boolean) specifies whether to synchronize the checkpoint data
for
the current job with the pages that have actually printed.  If this
attribute is
supported, a value of true implies that the Printer will be able to resume
the
job at the point of synchronization when restarted.

?) Is Reprocess-Job just like Restart-Job except that new "job-id" and
"job-uri"
are generated?
