After running into the problem of trying to find out what computers are using what network printers I created a report that will list all of the computers that have a specific printer installed.  This report can also be used to setup a dynamic collection of these systems.  This comes in handy when you look at what the prnmngr.vbs can do (which is a vbscript built into Windows for managing printers).  For more information about this go to http://technet.microsoft.com/en-us/library/bb490974.aspx. 

I was able to create a job in NS that would install a printer and delete another printer all based on the collections built with this report.

Since you can not attach .xml files just remove _.txt from the following attachment.
