I was using the Unity interface when I wrote the above.  In the Ubuntu
interface I do see 'printers' under Device in Settings.  However there are
two printers showing there and only one in the HP Device Manager.  I
deleted the second, non-working one from Printers under Device but it
returns immediately.

It is printing albeit it is barely putting ink on every other line.

Any suggestions appreciated.
