I have been using Ubuntu and Linux in general since 2001 and this is the first time that I have not been able to install my printer.
Approx a month ago I upgraded the system from 14.10 to 15.04 doing clean install of
/ partition, but not touching
/home partition. After booting into the system, the printer did not work. So I tried to install it by plugging it like dozens of times before, but it could not be recognized.
I tried HPLIP installation by downloading HPLIP for 64bit Ubuntu and when it came to
hp-setup part, I picked to install the USB printer, but HPLIP could not find it.
I switched multiple USB ports without success.
I even tried foo2zjs, but its local settings web page told me that I need proprietary driver to use this printer.
I am clueless as I have not idea how to install this printer which is 110% supported.
lsusb sees the printer and outputs
