Having issues with printers or printer drivers messing up your server or client? Here are some tips that can make your day better.

First of all, stop the print spooler service. After that, you can delete the following key depending on the printer or driver you are trying to delete.

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Print\Printers

Inside these registry keys, you can delete drivers that are not deletable using printmanagement.msc or control panel

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Print\Environments\Windows x64\Drivers\Version-3

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Print\Environments\Windows x64\Drivers\Version-4

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Print\Environments\Windows NT x86\Drivers\Version-3

If you get the error 0x0000011b on Windows 7 and later clients after updating your print server, here is a registry key that might help you:

HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\Print
DWORD RpcAuthnLevelPrivacyEnabled 0

The key needs to be set on your print server. Remember that by setting this key, you will effectively re-open the print nightmare security flaw by downgrading your security level on the server. If you want a persistent fix, you should use type 4 printer drivers, which do not need admin rights on the client side. Admin rights are needed if you have type 3 printer drivers.
