Remove-OldPrintJobs.ps1

# Jobs older than the below time will be deleted
$thresholdTime = (Get-Date).AddDays(-1)

# Get all current print jobs
$printJobs = Get-WmiObject Win32_PrintJob

ForEach ($printJob in $printJobs) {
  # Convert the weird WMI time to a proper .NET DateTime object
  $jobTime = [System.Management.ManagementDateTimeConverter]::ToDateTime($printJob.TimeSubmitted)
  
  # If the job's TimeSubmitted falls outside of the threshold, delete it
  if ($jobTime -lt $thresholdTime) {
    $outputString = "Deleting job {0} by user {1} submitted on {2}" -f $printJob.JobId,$printJob.owner,$jobTime
    Write-Verbose $outputString
    
    $printJob.Delete()
  }
