Cannot delete an old shared printer

I had a Mac set up with a printer shared on it. I used Bonjour Printer Wizard to then configure and connect to the printer from my Windows 7 machine. That printer is no longer on the network, so I went to delete it from my Windows 7 Control Panel, and clicked Remove Device, however, it doesn't remove it. What can I do?

I also have two other "versions" of the same printer on my Windows machine from when I originally was trying to set it up, and used the wrong drivers. I couldn't delete them then either, so I just went thru the Bonjour Printer Wizard again, until I finally got a driver that worked. In the end, I have 3 network printers "installed" on my Windows machine, only one of them worked. Now that I do not have a shared printer anymore, I would like to have all three of them removed, but they will not "delete". Any help s greatly appreciated.
