Delete global printer

How do you delete a global printer that is no longer connected to the server?
I have a printer that was installed by:
rundll32 printui.dll,PrintUIEntry /ga /n\\servername\printername

The server crashed and replaced by one with a different name. The commmand: rundll32 printui.dll,PrintUIEntry /gd /n\\servername\printername does not work apparently because the servername does not exist.
