 From my experience with a lot of HP printers over the years,
I'd suggest to
- use the socket backend (port 9100), as it seems the one
   most reliable. I don't trust the IPP implementations by
   printer vendors (HP, Xerox and others) too much.
- use the PostScript PPD unless you want to do printer
   maintenance by print jobs (which would require the hpijs
   driver). Usually all printing related operations are
   accessible vie PostScript, and maintenance is best
   dome using the printer's web-interface which all newer
   HP printers have.
