Bug Description
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/
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://
I also recently read that some distros are moving away from the GUI utilities to configure printers in favor of the CUPS web GUI , making this more relevant than ever.
edit---
On a second printer an HP Color Laserjet 2600N there is a similar issue using the foomatic driver as "Recomended" appears in some dialogs as if it is a recommended printer. The "recomended relates to it being the recommended of the three available drivers for this printer model.
