Not sure...  It depends on how it works, how you're using it.  I'll use
a Fedora system as an example, expecting that the Mac may be similar:

The server with the printer emits a broadcast on the LAN saying it's a
server with this printer.  The clients on the LAN receive this
broadcast, and make that printer one that the can print to.

The server needs its firewall open to allow the CUPS server to
broadcast, and for clients to connect to it, to print.

The clients need their firewalls opened to receive the broadcast from
the server, if they're to auto-configure themselves.

On the other hand, if you're manually configuring a client, telling it
the printer server address, they may be able to make a connection to the
server, without needing their own firewall opened to accept an incoming

Though, manual configuration isn't the way CUPS is intended to be used,
and can be a problem to manage.
