I deleted all printers and waited for CUPS / driverless to find them again.
Here a few CLI outputs (which are small enough so I dare to spost them inline )
$ ls -1 /etc/cups/ppd/
Kyocera_ECOSYS_P6026cdn.ppd
Kyocera-ECOSYS-P6026cdn.ppd
Kyocera_ECOSYS_P6026cdn.ppd.O
Kyocera-ECOSYS-P6026cdn.ppd.O
$ sudo systemctl stop cups-browsed
$ ls -1 /etc/cups/ppd/
Kyocera-ECOSYS-P6026cdn.ppd
Kyocera-ECOSYS-P6026cdn.ppd.O
$ sudo systemctl stop cups-browsed
I see 2 in the GUI, why there are 4 files here - I don't know why.
Seems that cups-browsed adds the "_" separated files
$ lp -d Kyocera-ECOSYS-P6026cdn ~/.bashrc

$ driverless

But where is the "get-printer-attributes-2.0.test" file - I cant find
this file.
$ ipptool -tv ipp://KM15881D.local:631/ipp/print
get-printer-attributes-2.0.test > ~/attrs.txt
ipptool: Unable to open test file get-printer-attributes-2.0.test - No such
file or directory
It seems so confusing to me as there are no reliable on/offs: sometimes the
files are available, sometimes not.
Maybe this outputs help a bit. Hope you see something in there.

Title:
"driverless" printer workflow has bad usability/ is partly broken
Status in gnome-control-center package in Ubuntu:
Incomplete
Bug description:
Hi,
since Ubuntu uses IPP ("driverless") printing, I have a bad time using
printers. I don't know exactly which package this bug belongs to, I think it is
gnome-control-center.
I have a Kyocera EcosysP6026cdn network printer, which provides a PPD
file by the manufacturer. (But I tested this behaviour as well with
other printers from eg. Brother, etc., and on Debian and Arch linux
too). When I switch on the printer, after a few seconds, it is found
in Ubuntu and installed automatically as "Kyocera_ECOSYS_P6026cdn". So
far, so good.
1) I can't remove this printer. If I WANT to install it using another
protocol (dnss etc), it adds another printer, and I have 2 Printers.
So it should be easy to switch off "driverless" printing.
2) Using it as "Default printer" does not work. Clicking the cog
wheel, and using the menu item "Use printer by default" is clickable,
but it does not save any setting: "printers-cc-panel-WARNING **:
20:45:36.812: cups-pk-helper: setting default printer to
Kyocera_ECOSYS_P6026cdn failed: client-error-not-found"
3) "Printing Options" opens an empty dialog, see screenshot attached.
This dialog is useless.
4) The "Printer Detail" dialog shows a "null" address and links to
"(null):631", which is a 404.
I think this "driverless" printing is still in a very "unstable" state. It
helps discovering printers in new Networks where I attach too with my laptop,
and I can print there basically, But most of the day I use my own printer in my
office or at home, and I want to have my special settings for exact this
printer with color profile, duplex settings etc.
And this all is not possible with driverless printing.
So, if you don't "fix" all the not-working options in the UI, please
at least give us an option to easily switch off driverless printing at
all. I really prefer the "old school" way of installing printers.
