Windows 2000 Print Driver Permissions for Users

In Microsoft Windows 2000, print driver installation permissions for non-administrative users depend on user group membership, the type of connection (local versus network), and active Group Policy settings. By default, standard users are restricted from installing local drivers to protect system stability, but Windows 2000 provides built-in mechanisms—such as the Power Users group and Point and Print functionality—that allow non-administrators to install drivers under specific conditions.

Default User Rights and Group Memberships

Windows 2000 enforces a strict security model regarding kernel-mode and system-level software, which includes printer drivers:

  • Standard Users (Users Group): Members of the standard Users group cannot install local printer drivers. Because drivers execute with high privileges, allowing standard users to install arbitrary drivers presents security and stability risks.
  • Power Users (Power Users Group): Members of the Power Users group have elevated local permissions. By default, they are permitted to install local device drivers, including printer drivers, provided the drivers are digitally signed or exist within the Windows driver cache.
  • Administrators: Members of the local or domain Administrators group have unrestricted rights to install, update, and remove any printer driver.

Network Printing and Point and Print

The primary method for allowing non-administrative users to install printer drivers without manual administrative intervention is Point and Print.

When a non-admin user connects to a shared network printer hosted on a Windows 2000 print server:

  1. The client machine queries the print server for the appropriate driver files.
  2. The print server automatically transfers the driver files to the client machine.
  3. Windows 2000 installs the driver locally in the user's context without prompting for administrator credentials.

This mechanism functions because the driver has already been vetted, installed, and trusted on the server side by an administrator.

Group Policy Controls

Administrators can override the default behaviors using Local Security Policy or Active Directory Group Policy objects (GPOs).

Prevent Users from Installing Print Drivers

Located at: Computer Configuration\Windows Settings\Security Settings\Local Policies\Security Options\Prevent users from installing print drivers

  • Enabled: Prevents members of the Power Users group from installing local printer drivers. Only Administrators can install drivers.
  • Disabled (Default): Permits Power Users to install local printer drivers.

Note: This policy applies specifically to local printer installation and does not block users from connecting to shared network printers via Point and Print.

Driver Signing Policy

Located at: User Configuration\Administrative Templates\System\Driver Signing

Windows 2000 checks the digital signature of drivers during installation. Administrators can set this policy to:

  • Ignore: Installs the driver regardless of signature.
  • Warn: Prompts the user before installing an unsigned driver (non-admins cannot bypass this prompt if it requires administrative consent).
  • Block: Completely blocks the installation of unsigned drivers.

Local vs. Network Installation Summary

  • Local Printers (LPT, USB): Standard users cannot install drivers. Power Users can install them unless restricted by Group Policy. Unsigned drivers require administrative approval if the system's driver signing policy is set to "Warn" or "Block."
  • Network Printers (Shared Queues): Standard users can connect to shared network printers and receive the necessary drivers via Point and Print without administrative privileges, provided the drivers are already present on the host server.
