I somehow managed to get a network printer working using a disposable virtual machine depending from an old Fedora 37 template that cannot be updated. I am not in condition to reinstall it on a newer Fedora template because I am old and every time I forget how to do it.
So I would be happy to isolate this dirty printing matter. How to do it using the GUI as much as possible?
Perhaps a firewall rule limiting to local network the network access of the …-dvm that depends on the fedora 37 template. Is it worth to do that? If yes, do you know how to write this rule?
You can add the firewall rule to restrict the network access to only your network printer IP address (and maybe port number if you know it) to the dvm qube like this:
192.168.1.0/24 netmask - access to any IP address in the range 192.168.1.0-192.168.1.255
192.168.1.1/32 netmask - access only to 192.168.1.1 IP address
