Workcentre 58xx Secure Print Display Name?

[CSHunt]

Just to clarify, it's the "Job Owner" that I wish to modify - but I can't find the setting anywhere in the Printer Properties for the 58xx devices.

We've just  implemented some new 5875 and 5845 devices to replace our older 5600 models. Now, on some of the machines, when print jobs are sent, some Secure, some not, the Windows username rather than the Novell username (we leverage iPrint) is being sent to the Xerox. This causes confusion, as most users login with a standard Windows username.

Is this configured somewhere in the driver properties?

We are using Xerox Standard Accounting.

Thanks, in advance.
