Hopefully not!

In particular hopefully not via WLAN!

See

In general:
Could you explain why you need to open any port in your firewall
for the external zone (i.e. for an external network)?

In particular:
Why do you need to allow in in your firewall to let your cupsd
be accessible from an external network (perhaps even via WLAN)?
