  I wrote this powershell script to print images. But when the script runs and starts to print I am getting empty page printout. I tried to use printdocument and graphics from .NET framework.This is my first time using powershell and .NET framework so I used these scripts for reference: script1, script2. I don't know what I am missing here. Any help is greatly appreciated.

  function Start-Print {
  
      $CopyCount = 1
  
      $pd = New-Object System.Drawing.Printing.PrintDocument
  
      $files = Get-ChildItem -Path "D:\Users\Phuntsho Wangdi\Desktop\New folder\unprinted\*" -Include "*.jpeg", "*.png", "*.jpg"
  
      foreach ($global:file in $files) {
  
          $file_name = Get-ChildItem -Name $file
  
          Write-Host $file_name
  
          $pd.DefaultPageSettings.PrinterSettings.PrinterName = "Canon E510 series printer"
          $pd.DefaultPageSettings.Landscape = $True
          $pd.PrinterSettings.Copies = $CopyCount
          $pd.DefaultPageSettings.Color = $false
          $pd.DocumentName = $file_name
  
          $action = {
              $bmp = New-Object System.Drawing.Bitmap("$file")
  
              #implemented from https://www.powershellgallery.com/packages/RoughDraft/0.1/Content/Send-Printer.ps1
              $newWidth = $bmp.Width * 100 / $bmp.HorizontalResolution
              $newHeight = $bmp.height * 100 / $bmp.VerticalResolution
  
              $widthFactor = $newWidth / $EventArgs.PageSettings.PrintableArea.height
              $HeightFactor = $newHeight / $EventArgs.PageSettings.PrintableArea.Width
  
              $widthMargin = 0
              $heightMargin = 0
  
              if ($widthFactor -ge 1 -or $HeightFactor -ge 1) {
                  if ($widthFactor -gt $HeightFactor) {
                      $newWidth = $newWidth / $widthFactor 
                      $newHeight = $newHeight / $widthFactor 
  
                  }
                  else {
                      $newWidth = $newWidth / $HeightFactor
                      $newHeight = $newHeight / $HeightFactor
  
                  }               
              }
  
              $heightMargin = (($EventArgs.PageSettings.PrintableArea.Height - $newHeight) / 2) / 2
  
              $EventArgs.Graphics.DrawImage($bmp, ($EventArgs.PageSetting.HardMarginX + $widthMargin), ($EventArgs.PageSetting.HardMarginY + $heightMargin), $newWidth, $newHeight)
          }
  
          $endprint = {
              $bmp.Dispose()
          }
  
          Register-ObjectEvent -InputObject $pd -EventName "PrintPage" -Action $action
          Register-ObjectEvent -InputObject $pd -EventName "EndPrint" -Action $endprint
  
          $pd.Print()
      }
      Write-Host "Done!"
