Question : How to delete/remove one of the printer port options from the drop down menu in the "Add Printer Wizard"?

I just finished setting up my pc to be able to use LPR printer ports.  After performing this I tried to add the IP and Port but I get an error telling me,
     "Specified oprt cannot be added.  The port already exists."

How can I remove the one already in the drop down menu and then setup my LPR port?

Close the wizard; got to the File menu in the Printers and Faxes window, open Server Properties.
Go to the Ports tab, and delete the port(s) in question. If there's a printer currently connected to the port, you'll first need to change the printer to use a different port, at least temporarily. You might have to restart the spooler service before you're able to delete the port.
