Once the printer/port is installed, I'd like to print a test page, capture whether or not printing the test page was (theoretically) successful, and display the result to the user.

Or is there a way to box this method so that what ever leak it has, is thrown out when it finishes. (like boxing it in a child process) using (ManagementObjectSearcher
