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

warning: Qt/PyQt 4 initialization failed.
error: hp-setup requires GUI support (try running with --qt3). Also, try using interactive (-i) mode.
Ok, i have found an answer for my question. So i'm posting it here, in hopes that it will be useful for another person:
For whatever bizaar reason the graphical interface of
hp-setup
is busted. So one needs to start:sudo hp-setup -i
The
-i
key is essential, because without it the setup doesn't proceed either. At this time i still haven't gotten the test page out, but the scanner is working properly, which is what i was needing originally.
