Printer drivers can contain trojans. The default level user should not have the ability to install drivers on a truly secure system. This tech-recipe describes how an admin can close this hole.
On Win2k, WinXP, and WinNT the default level user can install (potentially trojan) printer drivers.
This involves editing your registry. One should always export your current registry to backup and save it before editing.
Make this simple change:
Hive: HKEY_LOCAL_MACHINE
Path: System\CurrentcontrolSet\Control\Print\Providers\LanMan Print Services\Servers
Key: AddPrinterDrivers
Type: REG_DWORD
Value: 1
