Wireless HP Laserjet Professional P1100/ P1560/ P1600 on Ubunt Xenial Xerus

Or, thanks a lot, hp-setup!
As part of the re-install fest during last weekend, I also had to install the GF's printer on her Ubuntu lappie.
This time it wasn't as smooth as with Linux Mint, but not a real problem... In the end, the WiFi printer works A Ok.

At first it belched with an error message:

sudo hp-setup
sudo: unable to resolve host gf-lappie
[sudo] password for gf:

So, I went with the interactive install:
