Ira, I don't follow your logic here.  Disable-Operations with
"operations" ('Print-Job', 'Create-Job', 'Print-URI', 'Validate-Job')
is equivalent to the old Disable-Printer operation, right?  If so, then
the new operations are only useless if Disable-Printer was useless. 
Similarly, only users (Operators or Admins) that would have been
authorized to Disable-Printer would be authorized to
Disable-Operations.

There are really three roles:  Job-Submitting End User, Operator, and
Administrator.  These roles are not necessarily distinct.  A user with
a private office printer might play all three roles.

No disagreement here.
