Answer 1

Have you tried PrintQueue.QueuePort Property?

string default_port = DefaultPrinter.QueuePort.Name;

Update:

Then I recommend adding PrintQueue object to ComboBox

public MainWindow()
{
   InitializeComponent();

   PrintServer server = new PrintServer();

   foreach (PrintQueue queue in server.GetPrintQueues())
   {
      cboPrinters.Items.Add(queue);
   }
}

and using DisplayMemberPath for showing the FullName:

<ComboBox Name="cboPrinters"
          DisplayMemberPath="FullName"
          SelectionChanged="cboPrinters_SelectionChanged" />

In EventHandler you can get port name like this:

private void cboPrinters_SelectionChanged(object sender, SelectionChangedEventArgs e)
{
   PrintQueue printer = cboPrinters.SelectedItem as PrintQueue;
   string portname = printer.QueuePort.Name;
}
