more info here and here & download link here

Task Manager > Services > Right click "Airprint" > Start Service >

 I got this error:

The operation could not be completed.
The dependency service does not exist or has been marked for deletion.

And if I try to start airprint.exe manually I get a CMD window with:

Listening for connections on 0.0.0.0:631...
Unable to remove "C:\DOCUME~1\User\IMPOST~1\Temp\/cupslite/cupslite" - No such file or directory
XpdfPrint library version = 3.02.33

Solution:

Install Bonjour.

it is included with the iTunes installer, If you don't want to install the whole thing you can extract the iTunes installer and install Bonjour64.msi only.

GM Tech2 Diagnostic Tool cable pinout.....

After what seemed like a decade of hard work....
I -finally- found the correct pinout for the RS232 to RJ45 cable that connects the tech2 to my PC

here is the full story :-)

Basically only three pins are really required; they are

 RS232 --  RJ45 

    2       --      4   

    3       --      5   

    5       --      7   

2,3,5 are the Receive, Send, Ground respectively..
