Here’s a quick PowerShell script I put together to delete all print jobs from our Windows Server 2008 R2 print server. It’s run overnight as a scheduled task. We do this because sometimes our print accounting software doesn’t clear out old jobs if users haven’t released them at the printer.

$printers = Get-WmiObject Win32_Printer

if ($printers.Count -eq 0) {
    Write-Host -ForegroundColor red "No Printers Found"
    exit
}

foreach ($printer in $printers) {
    
    if ($printer.Local -and $printer.Shared)
    {
        Write-Host -ForegroundColor Green "Cancelling all jobs on: $($printer.Name)"
        $printer.CancelAllJobs()
        
    }
}

It will only clear print jobs on local printers that are shared out. There’s some more info about the Win32_Printer class and the CancelAllJobs method on MSDN.

Note that I haven’t included any error-checking in this script at all, so run it manually first to see if it will work. As always, run at your own risk.

To schedule it, simply create a new scheduled task:

1. Run with highest privileges
2. Run whether user is logged on or not
3. Do not store password
4. Action: Start a program: C:\Windows\System32\WindowsPowerShell\v1.0\powershell.exe
5. Arguments: -File “C:\path-to-script-file\name-of-script-file.ps1″
