No event is added to the System log or to an operational channel when a print job is canceled or deleted
No event is added to the System log or to an operational channel when you delete or cancel a print job on a computer that is running one of the following operating systems:
- Windows Vista
- Windows Server 2008
- Windows 7
- Windows Server 2008 R2
Therefore, you do not know whether the print job is deleted or canceled when you monitor the status of a queued print job by using the System log or the operational channel.
