Ubuntu 9.04: Why is IPP(TCP 631) open and how do I disable it?

I'm configuring a new install of Ubuntu 9.04 laptop and when I do a port scan, I find that TCP 631 (IPP) is open. What do I do to disable this listening port?

"CUPS, which is part of the Linux Standard Base, is enabled. To stop the service:

sudo /etc/init.d/cupsys stop

To disable it from startup:

update-rc.d -f cupsys remove
update-rc.d cupsys stop 20 2 3 4 5 ."

"Don't disable it, this is your printer!

To enable it again you can add port TCP 631 to your Firewall. Just type 631 in the Firewall.

More info at the Ubuntu Forums:

Thank you ! I have just deleted the port 631/tcp from FIREWALL because Facebook disconnected me alone wich gave me suspicions. So this was my printer !!! So just I'll just add again ALLOW IN TCP 631 inside my FIREWALL."

"if you want to stop that service use:

""sudo systemctl stop cups.service && sudo systemctl disable cups.service"""
