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):

  • @NOrbert thanks for the pointer, but that is exactly what I did :( And the fact that it did not work is why I posted all the diagnostic stuff. – user877841 Oct 3 '18 at 21:26
  • Please add what you've tried and what was the result. Until then the question will be closed as duplicate question... feel free to reopen it by editing your question tho. – MadMike Oct 10 '18 at 5:40

    The end result was (wish I could remember where I saw this suggestion): sudo apt-get install --reinstall libgs9-common Then printing worked, but scanning didnt. After that reinstalled hplip again, and now I can both print and scan! – user877841 Oct 12 '18 at 19:10
  • Same problem here with the identical printer .... I will report back if I can solve the issue that +user877841 suggestes regarding reinstalling libgs9-common. – rik-shaw Oct 25 '18 at 14:51
