Helpful Hints for Printing in Citrix® Using Xerox® Print Drivers
We recently installed a AltaLink C8170 MFP in our network. Installed on Windows 10 Pro using the Xerox Universal PCL6 driver 5.733.11.0. We have accounting turned on and enter the default account code in the configuration tab of the printer properties. No issues printing locally, but when this unit is mapped in our Citrix Xenapp session, the code is not being passed apparently and all jobs from the session fail with a reason of no accounting code supplied.
Looking for any documentation that will help us resolve this. Thanks.
