Printing on a Kyocero TASKalfa 356ci from Ubuntu 20.04 worked after specifying an official .ppf file from here.
However, printing from Ubuntu 22.04 using the same drivers results in black and white printouts. The default color settings from the Ubuntu-Settings-Printer-Menu is black and white, but changing it to color does not change the printouts.
From within the Ubuntu-Settings-Color-Menu, I tried to assign color profiles to the printer, but having assigned color profiles did not change the printouts.
How about trying driverless printing? This should have been automatically given to you, but it can be done manually.
Execute
driverless
to get a URI. Now substitute what you get for URI inlpadmin -p 356ci -v "URI" -E -m everywhere
and print to 356ci.
This seems to be due to a bug in CUPS:

See also this report on Launchpad: https://bugs.launchpad.net/ubuntu/+source/cups/+bug/1971242
A workaround suggested by a CUPS developer on GitHub is to issue the command:
lpadmin -p YOUR_PRINTER_NAME -o print-color-mode-default=color
