The printer/scanner worked when i was on the last LTS just fine (almost), but now after i've upgraded it tells me that it is unable to connect to the device.
I have attempted to do what HPPrinterInstallation says and i got the following:
$ gksudo hp-setup
HP Linux Imaging and Printing System (ver. 3.16.3)
Printer/Fax Setup Utility ver. 9.0
