For HP printers I have always got them working this way:

1. go to https://developers.hp.com/hp-linux-imaging-and-printing
2. download HPLIP for your distribution
3. execute the .run file
4. give your password when asked
5. answer the questions and perform the actions (read carefully)
6. create the NAME of your printer meaningfully (one word, plain ASCII)

When it's done (about 15 mins) go to http://localhost:631 and check that
CUPS can see your printer under the name you gave it under Printers,
then click on the name and select Test Page from the Maintenance menu.
Use the Administration menu to [re]set the defaults (eg paper size).
