Note that I have run through all the suggestions at How should I install HPLIP binary/proprietary plugin/driver for my HP printer or printer+scanner? and still have the same problem
Running 'Diagnose Queues' says Queue(s) configured correctly using HPLIP.
Running 'Diagnose HPLIB Driver' gives the following (which all looks fine to me):
