I suggest calling into the support department at 1-800-821-2797 to speak with an analyst for assistance with this.
I have my C8145 installed on Print Server and shared. I am deploying printer to users using Group Policy applied to a Active Directory security group.
Printer install but it installs with "Microsoft enhanced Point and Print drivers" so users are missing a lot of finishing functions under Printing Preferences.
I am using V4 drivers. If I use V3 the drivers fail to install because they need elevated prompt and I need to install this on lot of computers in a domain environment.
