This was still an issue as of today with Linux Mint 19. I installed the plugin manually as Afshan suggested and it worked for me.
Download the latest files here https://www.openprinting.org/download/printdriver/auxfiles/HP/plugins/ at the very bottom of the of the page find the latest files and copy them to a location you can easily remember to get to, from the CLI. Open a terminal and cd to the file location then just sh hplip-3.18.12.run and choose the right filename for the version you downloaded. Follow the instructions and it will load the missing plugin for you. Setup will then work as will all the other commands in Hp Device Manager -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to hplip in Ubuntu. https://bugs.launchpad.net/bugs/1749690 Title: hp-setup fails to install plugin Status in HPLIP: In Progress Status in hplip package in Ubuntu: Incomplete Status in hplip package in Debian: New Bug description: My HP printer requires a binary driver and the only way to install it is to run hp-setup from hplip package.
