Script to remove printers

by Jeremy on July 30, 2008

I wrote this script to help a customer cleanup user profiles and remove unsupported printers. This script can safely be executed in each user session and works a treat. It stamps the registry after the first time it runs, so that it can be left in place to capture all users, whilst only ever removing the printers once. A nice polite message box will appear to let the user know that their printers have been removed and tell them how to add new ones.

If, however, you find that some printers just cannot be removed, try my other script to remove orphaned/stale printer objects.

Enjoy!


Option Explicit

' This script will enumerate all printers and then remove the ones that do not match an array of printers that
' should not be removed. Nor will it remove any Terminal Server or Citrix client printer mappings.
' It will tatoo the registry to ensure it only runs once per user, which makes it easy to manage for the future.
' Note that there are two separate subroutines. One to remove network printers, and another to remove local printers.

' IMPORTANT: This script DOES NOT remove the drivers.
