Not to worry, actually you and Ted helped a great deal. Now that you
mention it being a hal or udev issue and thinking back to some of the
things I was noticing as I diagnosed the problem I think it may very
well have been a hal or udev issue.  I'll definitely keep that in mind
in the event I should have any future or similar issues with the
printing.

Much thanks...
