Maybe this will help:
Hidden feature code10 - Mask Job Name not honored via LPR
This problem has been resolved with version 071.xxx.034.06000_FE or higher software for the WC 78xx device. Please contact your Xerox Support Representative to obtain this software.
IMPORTANT NOTE: LPR/LPD settings must be adjusted on the WC 78xx WebUI to allow this feature to work properly.
Through the WebUI > Properties > Connectivity > Setup > LPR/LPD > Edit... > Advanced Settings > Select 'Enabled' for "PDL banner page attributes override LPR control file attributes for job name and owner".
Select "Save" after enabling.
Also note: The hidden driver feature "code10" must be set within the Print Management plug in (on applicable OS's) versus setting this within the Devices and Printers dialog to work correctly.
You can't set it like the old Fuji Xerox devices. You can just print via the GPD and use the special codes to mask the Job name
Open the GPD to Printer Properties > Administartion
on the keyboard tap CTRL + Shift + X to get the Special codes option
enter in code10 and click set
Printer Properties is a basic functionality of a Windows Vista and up v3 driver, which is what we are referencing here. You know to access a menu for something in Windows you need to right-click right?
