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 ;-)

The samsung ML-2010 does not have a postscript driver, it used a
samsung language II driver that is available on windows and linux. I
have read the samba-HOWTO-Collection document and config the mime.type
and mine.conv to accept raw printjob. However, the instructions are
hard to understand
1. Edit /etc/cups/mime.types to uncomment the line near the end of
the file that has:
#application/octet-...
2. Do the same for the file /etc/cups/mime.convs.
3. Add a raw printer using the Web interface. Point your browser at
http://localhost:631. Enter Administration, add the printer following
the prompts. Do not install any drivers for it. Choose Raw. Choose
queue name Raw Queue.
4. In the smb.conf file [printers] section add use client driver =
Yes, and in the [global] section add printing = CUPS, plus printcap =
CUPS.
5. Install the printer as if it is a local printer. i.e.: Printing
to LPT1:.(in my case /dev/usb/lp0) I did until this line
6. Edit the configuration under the Detail tab, create a local port
that points to the raw printer queue that you have configured above.
Example: \\server\raw_q. Here, the name raw_q is the name you gave the
print queue in the CUPS environment.
The line number 6 is not clear, i dont know what application they are
talking about for the "Detail tab". How can i create a local port and
point to the raw printer queue?
My goal is simple,
1/create a raw printer queue on CENTOS to accept any PREPARED print job
from any machine from the network
2/install a use samsung driver to prepare print job on CENTOS(same
machine where the printer is pluged into)
3/install and use windows samsung driver on windows machines to prepare
print jobs and sent them to the raw printer queue on CENTOS
Hope anyone can help
THAI
