Printer Driver Is Not Compatible If a Policy Is Enabled on Your Computer

When you run the Add Printer Wizard, you may receive the following error message after you click Finish at the end of the wizard:
Unable to Install Printer. The printer driver is not compatible with a policy enabled on your computer that blocks Windows NT 4.0 drivers. If you want to use this driver, contact your system administrator about disabling this policy.
This behavior occurs because Windows Server 2003 does not support Kernel mode print drivers by default.
NOTE: Microsoft Windows NT 4.0 print drivers are Kernel mode drivers.
To resolve this behavior, update the print driver on the print server so that it is not using a Kernel mode print driver.
To work around this behavior, use either the appropriate method:
Method 1If you are installing a Windows NT 4.0 print driver, contact your network administrator to have the policy removed.
Method 2If you want to install a non-Kernel mode driver locally for a remote network printer:
When you print to a network printer, Windows NT, Windows 2000, and Windows Server 2003 always use the print driver on the print sever if you are not using the local port workaround (method 2).
Kernel mode drivers are monolithic drivers that hook into the operating system at the kernel level. Windows Server 2003 and later versions include a policy that blocks Kernel mode print drivers because Kernel mode print drivers can cause the computer to display blue screen errors.
