Hope anyone can help ------------------------------------------------------------------------- ---------------------------------- 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.
