###### H.4.5.2.1.2 Behavior

The SCP uses the N-EVENT-REPORT to inform the SCU about each execution change. The SCP shall only use the N-EVENT-REPORT within the context of the Association in which the Print Job SOP Instance was created.

### Note

If SCU wants to monitor the complete execution process of a Print Job, then the SCU should only release the Association after the receipt of the event type Done or Failure.

The SCU shall return the confirmation from the N-EVENT-REPORT operation.

If the Event Type Name = Failure or Pending then the error/pending condition is stored in the Execution Status Info argument. The possible values of the Execution Status Info argument are defined in Section H.4.5.3.

If the Event Type Name = Failure or Done then the SCP shall delete the Print Job SOP Instance after receiving a confirmation from the SCU.

###### H.4.5.2.1.3 Status

There are no specific status codes. See PS3.7 for response status codes.
