My problem is very close to this one. I've installed updates KB2701894 & KB2748246 on client but it didn't help.
Server:
Windows 2012 R2 + current windows updates.
Xerox GPD PS (PCL, PCL6) 5.377.6.0
Clients:
Windows 7 x64 SP1 + current windows updates
Windows 7 x86 SP1 + current windows updates
GPO with Point and Print restrictions enabled.
Printers applies to users by Group Policy Preferences
Problem:
Xerox printers do not connect to clients. Every connection ends with event log errors.
HP UPD have not logged this error.
Details:
Event ID 601
The print spooler failed to download and import the printer driver from \\PRN-01 into the driver store for driver Xerox Global Print Driver PCL. Error code= 800f024b.
Event ID 600
