powershell print as another user

[ameyUK]

Hi there,

hope someone can help me with this problem please.. Below is a script to print a word document but i want it to print as different user not as user who is logged in..

$objWord = New-Object -comobject Word.Application
$objDoc = $objWord.Documents.Open("c:\test\new.doc")

$objDoc.PrintOut()
$a = $objWord.Quit()

A user will upload a file (done via php) with their username and password. then the php will pass the argument to powershell and I want the above script to print as that user using their authentication..

thank you so much
