If you're using IPP then 631 is enough. If you're using SMB then you
need to open ports 137 through 139 and 445, all tcp.

The printer is connect locally to the centos machine and should be 
shared to other windowsXP machines by samba. So when i config that 
printer on cenots, it is not IPP nor SMB but localy connected.
