Hello All, We have configured NPrinting Server and its working fine. Only for one task the status shows completed, but no email is sent to recipient. When we checked the log files, we can see that its showing, "receiving allocation from unknown engine" or "destination is not configured properly". But when we checked the configurations for engine and destination, those are same for other tasks which are working fine. Can anyone please let me know, what can be the issue. Regards, MK
