Paul L, I see, HAL and its CUPS backend were working around the problem that your printer does not return a usable device ID. HAL is deprecated now and therefore the hal CUPS backend is no part of Ubuntu any more. If your Panasonic is your only USB printer you can use the device URI
parallel:/dev/usb/lp0
as alternative in Karmic or Lucid.
One question: The Panasonic KX-P4410 is a rather old printer (PCL 4). Is this a native USB printer or are you using a USB/parallel adapter cable?
