Note: The printer driver is not compatible with a policy enabled on your computer that blocks NT 4.0 drivers.

• If the preceding policy is set to?? Enabled, change it to?? Not?? configured.

  OR

  If the policy is set to?? Not?? configured, change it to?? Disabled.

• Run the following command from the command prompt:

  Gpupdate?? /force

Note: You must not experience this?? issue if the policy is set to?? Not?? configured. However, the policy might be behaving like it is?? Enabled. Citrix Technical Support might ask you to set the policy to Disabled. If the policy is not behaving as expected, contact Microsoft Support.
Note: Windows 2008 blocks the installation of NT 4.0 (version-2) drivers.

If this?? Solution do not resolve the issue, this policy might be set at the domain level.

Citrix recommends customers to not use kernel-mode (version-2) drivers unless absolutely necessary as they can potentially crash a server. Instead, user-mode (version-3) drivers must be used exclusively to prevent crashes and maintain server stability.

A Windows Server policy named?? Disallow installation of printers using kernel-mode drivers?? causes this issue.
