I've posted the 16 slides that Carl-Uno will present tomorrow at the IPP
session at the IETF meeting. They are mostly on the Notification effort.
He will call me with any feedback that we should know about before the
Wednesday, 7/14 IPP telecon, and I'll present that.

IPP Notification Requirements
Scenario 1
* I am sitting in my office and submit a print job to the printer down
the hall. I am in the same security domain as the printer and geographically
near. I want to know immediately when my print job is completed (or if
there is a problem) because the document I am working on is urgent. I submit
the print job with the following attributes:
IPP Notification Requirements
Scenario 2
* I am working from home and submit a print job to the same printer as
in the previous example. However, since I am not at work, I cannot
physically get the print file or do anything with it. It can wait until I
get to work this afternoon. However, I'd like my secretary to pick up the
output and put it on my desk so it doesn't get lost or miss-filed. I'd also
like a queued notification sent to my email so that when I get to work I can
tell if there was a problem with the print job. I submit a print job with
the following attributes:
IPP Notification Requirements
Scenario 3
* I am sitting in my office and submit a print job to a client at an
engineering firm we work with on a daily basis. The engineering form is in
Belgium. I would like my client to know when the print job is complete, so
that she can pick it up from the printer in her building. It is important
that she review it right away and get her comments back to me. I submit the
print job with the following attributes:
IPP Notification Requirements
Scenario 4
* I am in a hotel room and send a print job to a Kinko's store in the
town I am working in, in order to get a printed report for the meeting I am
attending in the morning. Since I'm going out to dinner after I submit this
job, an immediate notification won't do me much good. However, I'd like to
check in the morning before I drive to the Kinko's store to see if the file
has been printed. An email notification is sufficient for this purpose. I
submit the print job with the following attributes:
IPP Notification Requirements
Scenario 5
* I am printing a large, complex print file. I want to have some
immediate feedback on the progress of the print job as it prints. I submit
the print job with the following attributes:
IPP Notification Requirements
Scenario 6
* I am an operator and my duties is to keep the printer running. I
subscribe independently from a job submission so that my subscription
outlasts any particular job. I subscribe with the following attributes:
IPP Notification Requirements
Scenario 7
* I am an printer statistics application. I subscribe independently
from a job submission so that my subscription outlasts any particular job.
My subscription may persists across power cycles. I subscribe with the
following attributes:
IPP Notification Solutions
* Subscription:
* As part of IPP Job Submission (for single Job)
* As independent Operation (for Printer and all Jobs)
* Notification Format:
* Machine friendly: application/ipp MIME format
* Human readable: text format (email)
IPP Notification Solutions
* Notification Transport:
* Simple UDP, without confirmation
* Email, with or without confirmation
* Other, such as HTTP
* Other Notification Criteria:
* Reliability
* Delay, Frequency, Repeatability
* Security
