 The communication protocol used is the **Internet Printing Protocol** over **TPC/631** port. When adding the printer via the CUPS administration page, specify the URL like **%%ipp://192.168.3.3:631/ipp/print%%**. The printer should be discoverd as **HP Color Laser MFP 179fnw, driverless, cups-filters 1.28.17**.
+If you want to check that the printer can be correctly discovered on the local LAN, use the command:
+<code>
+avahi-browse --all --resolve --terminate
+...
+=   lan0 IPv4 HP7C4D8F8963CC (HP Color Laser MFP 178 179)   Internet Printer     local
+   hostname = [HP7C4D8F8963CC.local]
+   address = [192.168.3.3]
+   port = [631]
+</code>
+The name HP7C4D8F8963CC can be resolved using **nmblookup** too:
+<code>
+nmblookup HP7C4D8F8963CC
+.168.3.3 HP7C4D8F8963CC<00>
+</code>
+So the URI used by CUPS can be **%%ipp://HP7C4D8F8963CC.local:631/ipp/print%%**, that will work also if you change IP addresses in your LAN.
+Here it is the PPD file generated by CUPS: **{{hp-color-laser-mfp-179fnw-ppd.zip|hp-color-laser-mfp-179fnw-ppd.zip}}**.
