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)
HP printers are bitchy about using non-HP branded ink carts (or tonor carts). HP is very interested in extracting their "pound of flesh" for all eternity.
It does not say which one or why this would cause communication failure.
How do I figure this out?
You will have to "easter egg" it. Swap the carts out one-by-one with new, HP carts until the error goes away.
