Windows Service application unable to send print job

I've been trying to send print job into a remote printer via a Windows Service application in a few different ways: 

• .Net PrintDocument class
• a third party library (on-demand printing)
• ghost script + ghostview

however I was not successful. I found out that Windows Service doesn't allow you or doesn't easily allow you to send or create a print job at all for security reasons or for any reasons. See posts:

Well another day past and some lost hairs (due to hair pulling) I found a web post about a utility class that creates a "Raw" print job and I thought it may work because Windows won't treat it as calling or executing another windows app or windows process which the Windows Service doesn't like to do. So I give it a go and it works! See the section of the page where it says "2. Mit VB.Net RAW-Daten an den Drucker senden" which translate to "Send With VB.Net RAW data to the printer". (Note: The website is in german language. Thank you Germany!)
