I had to install my HP OfficeJet in Ubuntu 15.04. I need it to scan and print using the printer’s wireless function and to do that you need to install HPLIP as per my below video. The articles I used are: http://hplipopensource.com/hplip-web/install/manual/distros/ubuntu.html and http://hplipopensource.com/hplip-web/install/manual/hp_setup.html ( I had to run sudo hp-install -i to setup the printer as I received GUI errors and was not in the mood to find out why)
