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??

Welcome to LinuxQuestions.org. Some questions...

1. I assume that the printer is network-connected?

2. Can you show us your working configured CUPS printer URI for both the Mint and Fedora distros?
3. Is the printer enumerated with the following command?
4. Do you have an active firewall on the Fedora OS? If so, please show us the output of
https://docs.fedoraproject.org/en-US...ocs/firewalld/

Hey thanks for responding, I found better application that helps ID the cups + samba share. The gnome printer gui for Fedora 34 is not that great, and found one better! but off hand can't remember the new app.

take care

Ok, well not obvious what your issue was (not enough info provided), but reads like all is now working anyway.

I figured out how to configure the Cups server on my server machine, but on the Fedora 34 client, one printer would not work, and wondered if there was an issue with the Gnome system-printer-config gui, though the printer worked on the Mint client OS, dual boot w/ Fedora and Mint, so if the Mint client worked then the issue was the Gnome app in Fedora, so I just used another app one I use in Mint or Debian based client, and lo and behold it worked, use of cups and samba, now I need more ink! its an old Epson Xp-400 ink jet but glad I didn't have to do anymore configuring of the cupsd.config file, I learned a lot from you tube

Cheers!

I don't use samba for printing between linux systems. Setting cups for sharing printers will let other linux see and allow remote printing. You do need to allow access to cups port 631 through the firewall.

Nice story, but missing definitive info, so only speculation is possible.
