Does IPP have a "position" on either per-job (i.e. if job is spooled) or
per-printer subscriptions and whether or not they should be preserved
across power cycles?
Looking at the Notification Spec (draft-ietf-ipp-not-spec-07) the only
related discussion appears to be in Section 5.4.3 (When the Printer powers up, it MUST set the value of this
(notify-lease-expiration-time) attribute in each persistent Subscription
Object...) which implies per-printer subscriptions may be expected to persist
across power cycle.
