I have a Samsung printer(ML-2010) connect to my centos 4.2 machine by usb. I want to share this printer with 3 windowsXP mchines in my LAN. Although i have install driver for the printer on all machines, use samba to share the printer, from the windows machine i still have an error"access denied, can not connect to printer" or something similar. In Security Level, i have checked "trusted device: eth0, sit0" , is port 631 automatically open? How do i know that my problem is not caused by the blocked port? 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.
