Subject: IPP> About notification
Hello all,
Could someone please clarify these doubts pertaining to
Notification operations:
1>In the Print-job request, does the sequence in which Job
template attributes and Subscription attributes occur matter?
TH> The Subscription Attribute Group MUST come after the Job Attribute
Group, since all operations indicate the order that groups MUST be sent.
2>I have understood the following attributes in Send-Notification
request [indp: delivery method] to be mandatory. Are these correct?
TH> Yes, except as noted.
Group1: Operation attributes: attribute-charset
attribute-natural-language
notification-recipient-uri
Group2 to N:Notification attributes:
notify-subscription-id
printer-uri
TH> In order to be consistent with Subscription object names and to not have
duplicate attribute names in two different objects, we agreed to put a
"notify-" prefix on this attribute making it: "notify-printer-uri" for both
the Subscription object and what is sent in the Event Notification content
(for INDP).
trigger-event
TH> We agreed to rename this: "notify-trigger-event" so that all Event
Notification content attributes start with "notify-", unless they are copied
from some other object (other than the Subscription object).
printer-up-time
job-id
job-state
job-state-reasons
TH> The 3 above are only for job events.
TH> And "job-impressions-completed" is MUST for 'job-completed' and
'job-progress' events
printer-state
printer-state-reasons
printer-is-accepting-jobs
TH> The 3 above are only for printer events.
Kindly let me know if there is any attribute missing/redundant.
TH> If the Subscribing client supplied notify-user-data (octetString(63))
you MUST send: notify-user-data
TH> There are also the following RECOMMENDED and OPTIONAL attributes for the
Notification Source to support in the Send-Notifications content:
notify-text RECOMMENDED
notify-sequence-number RECOMMENDED
printer-current-time REQUIRED if you
support it
TH> Also if the Printer implementation supports the OPTIONAL
"notify-attributes" Subscription Template attribute, then the Printer
includes the additional Job and Printer attributes that it supports in Event
Notification as well.
thank you,
Vinod
