FreeFlow Output Manager sends Status Signals to the MIS 
through a persistent channel. The MIS sets up a persistent 
channel by sending a Status Query message with a Subscription 
element.

The subscription identifies a URL which shall be registered for this 
controller. Once the persistent channel is established, it remains 
open (across system restarts) until a StopPersistentChannel 
message is received.

The StopPersistentChannel message unregisters a listening 
controller from a persistent channel. No more messages are sent 
to the controller once the command has been issued.

The FreeFlow Output Manager sends a JMF Status Signal to the 
subscribers for each of the following conditions:

•

Job forwarded to printer

•

Job at printer, but held waiting for resources (media, finishing)

•

Job printing in progress

•

Job printing stopped while waiting for resources (media, 
finishing)

•

Printer connection lost

•

Job Completed

•

Job Aborted

The ReturnQueueEntry command returns a jdf file that had been 
submitted with a SubmitQueueEntry command. This command is 
sent by the FreeFlow Output Manager after the job completes or 
aborts. The Audits and JDF/@Status of the JDF that is being 
processed shall be set to "Completed" and the JDF delivered to 
the URL as specified by SubmitQueueEntry/@ReturnJMF.

Output Manager will attempt to send a ReturnQueueEntry 
command multiple times, until such submission is successfully 
received by the client. This allows a temporarily down client the 
time to regain operation. Send attempts will also be made at 
preconfigured time periods, assuming that it may take some time 
for the client to resume proper functionality (for example, during a 
reboot). Both the time period and number of attempts are 
configurable.
