$pdftoprint=""
$printername="ET0021B7219675"

$scanlogname = Join-Path -Path $scanlogdir -ChildPath
"$($MyInvocation.MyCommand.Name)-$(Get-Date -Format 'MM-dd-yyyy').log"
echo "$(get-date) - Checking for any scanned pdf files in $scandir" | Out-File -Append $scanlogname

Get-ChildItem -Path $scandir -filter "*.pdf"| % {
$pdftoprint=$_
