My use-case for cloud printing
Title:
Student Printing Homework at Friends House.
Description:
John, a high-school student, rushes out of the house on his way to his
friend's (Steve) house and, then, to school. In less than 5 minutes he
arrives at Steve house. Steve waves his history report at John to show
him it is done and printed. John reaches in his backpack to realize he
has forgotten his printed copy. John tells Steve he has a copy of his
report on his cloud and could he print it at his house. Steve agrees.
Steve ask John for his cloud user name and adds John as a 'friend' to
his cloud aware printer. John promptly logs into his cloud account and
finds his history report. Invoking a print request, John sees that
Steve's printer has been added to this printer list. Selecting Steve's
printer, John prints his report and they are both off to school.
Optional: Steve's system administrator (dad) does not want the
'friend's' list for the printer to be to long; so, Steve removes John
from the 'friend's' list and John see the printer disappear from this
printer list.
Goal:
To demonstrate rapid but temporary access to cloud print services and
the necessary administrative services
Actors:
John, using his cloud account and cloud print service
Steve, using his cloud account and cloud printing administrative service
Assumptions/
Preconditions:
1. John and Steve both have cloud repositories accounts.

5. John sets his print options and presses the print button.
6. The print dialog generates a Print-Job-Ticket and records the URI for
Steve's document in the Print-Job-Ticket.
7. The print dialog passes the print request to the cloud repository

10. The cloud repository print client manager receive a print-complete.
11. The cloud repository print client manager updates John's print

Process:
Alternative:
1. Steve logs in to his cloud account
2. Steve removes John from Steve's home printer 'friend's' list.
3. The cloud system remove Steve's printer from John's printer list.

Subject: [Pwg-Announce] Call for use cases
All,
Based on our discussions during the Cloud Imaging and IPP WG sessions, I
am calling for all PWG members to send in a single use case for
printing, scanning, or facsimile for Cloud and/or IPP Everywhere. Please
be as specific and detailed as you can, and cover everything from the
installation/setup of the printer to any status/error/progress.
