Hello community! I have issues with the mass deploy of workcentre 5335. I'm trying to do that via Group Policy of Windows Server 2008 R2. I have set in either printer defaults and preferences 1-side printing, but on a client PC it's always 2-side. Client's OS is from Windows XP to Windows 8.1, both 32 and 64 bit. I have try to use another driver. I have try to make the registry entry, RepositoryUNCPath, but it's didn't help as well. Also, I have try to replace Workcentre driver files, but it's didn't help too. Please help.
