With the Deskjet D1420 disconnected, hp-probe
finds no USB printers (duh).
With the Deskjet D1420 connected, hp-probe
finds it.
hp-testpage produces
error:  Unable to communicate with printer Deskjet-D1400-series.  Please check 
the printer and try again.

Note that hp-probe found it.

hp-testpage also produces a popup saying ...
There is a problem with a print cartridge (1017)

It does not say which one or why this would cause communication failure.

How do I figure this out?
