Fedora 34 -- cups issue with client machine

I got cups to work on my Mint Client with the Epson XP-400 printer, however when I try to use Fedora 34 (I have a triple boot OS system) I can't seem to get cups under the Fedora client to work, and use the same configuration, opened the ports in the firewall, but nothing helps.

I like the new Fedora 34, w/ the Gnome 40 and only use the Mint 20.04 client for printer both printers on the server side, using Samba and Cups

any suggestions? is there something about Fedora I should know about, perhaps the kernel is too recent 5.12??
