The    
"printers.vbs" script

Introduction

The script below includes code for deleting existing printers.
That feature has been added temporarily in order to clean up
printers that were inadvertently installed due to improper
permissioning. That portion is disabled to avoid long logon times.

Implementation

This script is called from the main co-managed "LoginScript.vbs"
script and runs for all non-"IF-ADM" accounts.
