CentOS - Mar 2006 - Do i have to open port 631 for LAN printing

Hi,
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
Thai

windows doesn't use cups port

error message of 'access denied' doesn't necessarily mean that
Windows
users can't print to it (that's very confusing, I know) but that
certainly means that the users can't "manage" the printer.

in samba printer share, there is an option for 'printer admin' which if
the user/group is appropriate, will allow the user/group to 'manage' the
printer, which is generally where the 'access denied' message comes from
in a samba shared printer when looking at the 'status' from Windows
'Printers & Faxes'

Generally, I would expect the problem that you are having is that you
are using 'client side' drivers and by default, cups (via samba) is
offering a postscript printer.

I don't know what the specifics of a Samsung ML-2010 are but it would
seem that you have 2 options...

1 - set the printer up in windows as a postscript printer, preferably
using the Adobe Postscript print driver and the ppd that was created by
cups on the CentOS system when you created the printer (located
in /etc/cups/ppd)

or

2 - set the printer options within cups to allow 'raw' printing - which
allows your samba shared non-postscript printer commands to pass through
'unmolested' to the printer (see /etc/cups/mime.types
& /etc/cups/mime.convs)

All of this is summarized in the official Samba 3 HowTo...
http://samba.org/samba/docs/man/Samba-HOWTO-Collection/CUPS-printing.html

and things are starting to gel at the new samba wiki
http://wiki.samba.org

for which printing support is here...
http://wiki.samba.org/index.php/Samba_as_a_print_server

and I mention the wiki because I was drafted and am the editor of the
wiki ;-)

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.
