Scripting printer installation through a dynamic shutdown script

Many would think that using scripts to install printers might be a thing of the past thanks to Group Policy Preferences and other methods of deploying the beasts. However, the versatility of using a script and not having to establish a print server is still quite useful in many environments. Part of that project I mentioned previously had me querying printers throughout the organization. The next part of the project was to create a script that would be able to install the replacement printers as hands-off as possible.

To make the script flexible and simple, I wanted the printer installation to be based on Active Directory group membership. No printer would be installed on all computers and all computers could get a variety of printers installed. Therefore, I needed the script to determine the local computer’s machine name and its group membership in Active Directory. It then goes through each group to see if it is one of our printer groups. If it is, the script creates the printer port, installs the correct driver, and then creates the printer. I didn’t want the printer install taking place every time, so I used a check against the Registry to see if the port still exists. Checking this would allow the user to safely rename the printer as they prefer but does have some quirks as Windows XP leaves the printer port if the printer is manually deleted while Windows 7 removes it. If the user deletes the printer and doesn’t want it reinstalled, they just need to request their computer to be removed from the group.

The script was found to be most reliable running as a shutdown script, assigned to all computers through Group Policy.

To extend the functionality of the script to work for more printers, it is simply a matter of copy+pasting the Case statements below and setting the correct variables.

I investigated other methods of installing the printer like the Rundll32 printui.dll,PrintUIEntry method and utilizing the included printer management scripts that come with Windows. Ultimately, I found the WMI method to be the most consistent without needing elevation or other hurdles to be jumped. You can see my implementation of the script I’m using below.
