Hi, i found the the same problem, but my printer is a Samsung C480X. The printer works normally great under 20.04, but after update no color printing anymore. Under 20.04 i install the Samsung ULD driver from the Samsung (HP) web site.
What i found (unfortunatly i had no time to look deeper in the function); I think, the problem is not a problem of the printer driver or ppd-file. If you start with a fresh install Ubuntu 22.04, printers are found by cups-browsed, no matter if network printer or usb printer. Also the Samsung C480X will be found (without installing the Samsung ULD printer driver). My point of intrest was the network printing. With the system-config-printer i set up the printer as "implicit://<printername>" and set the driver to cups driverless. With this configuration the printer could produce colored pages. The cups web interface (http://localhost:631) and kde-printer show the new installed printer correctly. Before this i changed the printer name with the web interface of the printer from Samsung C48x (SEC12345678) to SEC12345678. This name has no blanks and () in it and seemed to be better appropriated by cups. But: After reboot cups-browsed (is my assumption) rewrites the file /etc/printers.conf and you have to configure the printer again. Q&D Workaround: (not for production) Set using chattr "i"-Flag for printers.conf*, and it works fine. Perhaps somebody is able to find the error in the cups-system.
