===== Embedded web server admin password =====

:!: **WARNING**: To login into the EWS (Embedded Web Service) you need to point a browser to the printer URL using the **IP address**. Do not use the name eventually assigned by your DNS server or a static name defined e.g. with a static entry into the hosts file: in this case the login will fail wihtout any error message (System Firmware Version V3.82.01.14 FEB-04-2022, 
UP Version 1.16.7.20190114.141254, Engine Firmware Version V1.00.14 2019-03-04, UI Firmware Version V3.79.05.13).

===== 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
192.168.3.3 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:

<code>
scanimage -L
device `escl:https://192.168.3.3:443' is a HP C4D8F8963CC (HP Color Laser MFP 178 179) platen,adf scanner
</code>

All the supported options supported by the device can be discovered with:

<code>
scanimage --device-name 'escl:https://192.168.3.3:443' --all-options
</code>

A typical command line to scan from the **flatbed** is:

<code bash>
scanimage --device-name 'escl:https://192.168.3.3:443' \
    --buffer-size=1M --format=tiff \
    --batch='page_%03d.tif' --batch-start 1 --batch-count 1 \
    --mode 'Color' \
    --resolution='300' \
    --source='Flatbed'
</code>

Scanning through the **automatic document feeder** can be accomplished with the command:

<code bash>
scanimage --device-name 'escl:https://192.168.3.3:443' \
    --buffer-size=1M --format=tiff \
    --batch='page_%03d.tif' --batch-start 2 \
    --mode 'Color' \
    --resolution='300' \
    --source='ADF'
</code>
