 ===== Printing with GNU/Linux =====
+Printing is supported through the **image/urf** image format, which is an Apple raster format used for AirPrint. **CUPS** 2.4.2, which is included in **Debian 12 Buster**, does support URF.
+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}}**.
+===== Unified Linux Driver =====
+From the HP site you can download the proprietary **HP Unified Linud Driver** for this printer. Unfortunately this is a binary-only package, although compiled for various architectures (aarch64, i386, mips64 and x86_64).
+The included PPD file for the printer uses the **rastertospl** cupsFilter.
+FIXME What are the advantages on using this proprietary driver instead of the open source URF support provided by CUPS?
 ===== Scanning with GNU/Linux =====
+This scanner is supported through the AirScan (eSCL) protocol, so it is necessari to install the **sane-airscan** Debian package to allow the **scanimage** program to access the scanner itself.
+It is possibile to autodetect the scanner when the multi function printer is powered on and connected to the local network:
