Public bug reported:
First I do not know if this is a CUPS issue or an Avahi issue.
I do not know whether Avahi or CUPS generates the files nor where they
are. They are not in /etc/avahi/services, where I expected to find them,
so they must lie somewhere in CUPS.
I have a printer installed in CUPS. I must use the driver from a
different model to make it work. Among other things I want avahi and
CUPS to show the printer name, consistently unless related to the print
driver used.
avahi-browse shows
Xerox_Phaser-6125 @ Hostname (correct)
Later however in Txt fields avahi-browse shows "product=(DocuPrint C525
A-AP)" .......... "ty=FX DocuPrint C525 A-AP v1.0" (incorrect printer
model but is the driver in use. Those fields relate to Product and type,
not driver)
The problem above I suppose is the "trickle don effect" from how CUPS
names the printer. In the CUPS web GUI I see
Queue Name Description Location Make and Model
Status
Xerox_Phaser-6125 Xerox_Phaser-6125 Home FX DocuPrint C525 A-AP
v1.0 Idle - "Waiting for printer to finish."
The Make and Model is not Make and model at all, rather it comes from
the driver used. I know it is commonplace to use say an HP LaserJet PS
driver when you want PostScript , like back in the day when I printed to
a LaserWriter, so I am not the only one that sees this.
Also, I think there should be a proper "representation" in the txt
fields as well icon as is done with AirScan/eSCL scanners advertisements
"representation=http://HOSTNAME./images/Icon.png"; as I believe some apps
will use this icon of the actual printer. This field should not be
required but optional. These days we connect many different OSs to Linux
and expect Linux to "do it all", and we still want it to look pretty and
correct. I know Apple in some cases uses the "representation" field.
This "representation" field too would have to tricke down from CUPS to
Avahi, as Avahi would only point to the file at
http://HOSTNAME:631/images/Icon.png. So it needs to hosted on the CUPS
web GUI.
I also recently read that some distros (Debian?) are moving away from
the GUI utilities to configure printers in favor of the CUPS web GUI ,
making this more relevant than ever.
