Turn off the AirPrint feature on all printers.  However, this cannot be done because of the RPC error within the Management Console.  Micro Focus support can do this for you.  Micro Focus support engineers can access the OrientDB to turn off the AirPrint feature on the printer (or printers). 

Micro Focus engineering is evaluating this problem. They plan to come up with a code update which will prevent this problem from occurring.


A bug in the code which affects AirPrint printers and submitting large print jobs through AirPrint.
