I've acquired an HP Officejet 6310, and am pleased to note that it should work with Linux.
I have downloaded hplip-2.8.12.tar.gz. However, I note from Gslapt Package Manager that there is already a version of hplip installed - it's 1.7.4a-i486-2, and Gslapt mentions version 2.7.12-i586-5vl59 being available but not installed.
Q1. Should I install the latest version and, if so, how do I do that?
Q2. Does hplip bypass the CUPS printing system, which I have running my Epson Stylus Photo 890 (not very well)? Or does hplip have to be incorporated into the CUPS system?
