You could try System Restore to a date/time before you installed the Logitech web cam, but of course that would uninstall the web cam.

Or, if you still have the printer software setup CD, disconnect the printer with the computer turned off, then start the computer and boot into Windows, uninstall that printer, reboot again and use that CD to reinstall the printer software. Then re-connect the printer.

That might work.
