I used the add printer dialogue on Ubuntu Linux but I didn't manage to install a HP deskjet 2514 printer. Following a recommendation read on Ubuntu-fr doc I installed the HPLIP tools (HP Linux Imaging and Printing). And it worked, I can now print and scan from Ubuntu on this cheap Deskjet printer. Once HPLIP is installed, new HP printers can be installed using the command: hp-setup.
Printers installed on the local computer can be accessed through: http://localhost:631/printers/
Next step is to plug the printer to my internet router to enable printing through the wifi. My internet router has a windows printer sharing capability. On Lubuntu I needed to install the smb client to be able to access a printer shared on a Windows network.
HPLIP Installer ver. 5.1
Enable the universe/multiverse repositories. Also be sure you are using the Ubuntu "Main" Repositories. See: https://help.ubuntu.com/community/Repositories/Ubuntu for more information. Disable the CD-ROM/DVD source if you do not have the Ubuntu installation media inserted in the drive. During the install process you will be added to the lp and lpadmin group, please quit the installer before the setup stage, log out, log back in, and run hp-setup to complete the install.
