Clean Up Unused Printer Drivers

Working on a printer migration project, and one of the first steps was to clean up the existing print servers so that when running the migration. I wanted a way to contact remote print servers too. This script, once imported allows cleanup of remote print servers.

Requires Powershell 4, so run off a Windows 8/Windows Server 2012.

If targeting a Windows 2003 print server, it cannot perform the actual removal and will just list a number of errors. It does atleast highlight all of the drivers which are not in use though.

$Drivers = Get-PrinterDriver -ComputerName $PrintServerName
$Printers = Get-Printer -ComputerName $PrintServerName

ForEach($Driver in $Drivers)
{
$PrintersUsingDriver = ($Printers | Where {$_.DriverName -eq $Driver.Name} | Measure).Count
Write-Host "Driver: $($Driver.Name) has $PrintersUsingDriver printers using it."

If ($PrintersUsingDriver -eq 0)
{
Try
{
Remove-PrinterDriver -Name $Driver.Name -ComputerName $PrintServerName -ErrorAction Stop
