Ok, lets take this from the top. The cupsd.conf should have only one
Listen statement in most cases, and that is:
Listen 127.0.0.1

Clients on the same LAN will be able to print to the printer without
any further configuration. That is , no server line needs o appear in
the clients.conf file. Further, if the Server line appears in the
client.conf file then the client will not be able to print to a local
printer.

Under no circumstances should system-config-printer be used to
configure CUPS printers. It has serious flaws for this purpose.

If the original poster used system-config-printer to configure the
server printers this is one reason printer might have not worked on
the clients.

That Listen address means for the machine to listen to itself, not to
the local network.  You'd need something extra for it to listen to the
LAN.

I agree, note my post in the original thread.

I have proven this several times in the last 3 months, I also noticed
that I have had to keep a backup of my cupsd.conf file on the server,
as every so often (and completely on it own) the server will fall back
to an original configuration file and my systems will be unable to
print to that printer, I simply copy my backup to the cupsd.conf file
and restart cups and voila.

Do you have the cups-config-daemon running?  It automatically
reconfigures CUPS in some way that I've not seen detailed.

FC4, at least.  Did you think we were discussing something other than
Fedora on this list?  Are you so vehement against HAL, Kudzu, and other
auto-config tools?  At least this one can be disabled without causing
any woes, so far as I can tell.  Things like udev and HAL we're stuck
with.

So far the only description I can find of it is what's written into the
system configuration GUI (This is a daemon for configuring printers
through D-BUS).  I've found no documention, just websites where people
have attributed it to problems, and instructions to turn it off.

Yes. It is running and automatically destroys whatever I could change in
cupsd.conf file to have my system working properly.

We have no information about this daemon: who starts it, how to stop its
nuisances, etc.

Every man about cups system refer to
http://localhost:631/documentation.html

I can read in http://localhost:631/sam.html#7_3

(Sorry for the French, I cannot find this in english! in german,
spanish, but not english!)

Changer la configuration du serveur

Le fichier /etc/cups/cupsd.conf contient des directives de configuration
qui contrôlent le fonctionnement du serveur. Chaque directive suivie de
sa valeur est disposée seule sur une ligne. Les commentaires sont
ouverts par le signe dièse ("#") au début de la ligne. Etant donné que
le fichier de configuration du serveur est un fichier texte, vous pouvez
le modifier au moyen de votre éditeur de texte préféré.

I translate the last sentence:

You can modify it (cupsd.conf) with your preferred text editor.

Why this possibility and why should I try to do so if
"cups-config-daemon", systematically destroy my work?

If they are more harmful than useful, yes, we must be vehement against
them.

How to? as you say it yourself later on: there is no documentation!!!!

So, something is to be changed in Fedora distributions!

Humm, unless FC4 has seriously fouled its nest, one really should be 
able to do something along the lines of this from a root shell:

#>chkconfig cups-config-daemon off
#>service cups-config-daemon stop

And it should be stopped forever.

The cups-config-deamon problem was discussed on the list back in
August 2005.  Check this CUPS article for more information:

OK. I read it. Find that the daemon comes from hal-cups-utils package.
Checked the content of the package and did not found any reason or
justificatio to the utility of such a package......

I stopped the daemon, and removed it from list of services launched at
start-up. What will happen to me now? We'll see later!

Thanks.

The cups-config-daemon is started like other ones.  If you use the
command line, you can play with chkconfig; and if you use the GUI, it's
listed in the "services" Gnome configuration whatsit (I don't know what
KDE offers, I don't have it installed).

I stopped it on one of my PCs ages ago.  I don't recall having any
problems with that PC.  I don't think it gets started by something else,
such as starting CUPS starting it up as well.  I don't have that PC
running to look at what it's doing anymore.

Judging by what I think it's supposed to do, I wouldn't run it on a
server unless your server kept having printers changed on it.  I might
run it on remote terminals so that they can find the LAN printer all by
themselves.  I was pleasantly surprised to see a FC3 box do that:  I
installed FC3 onto a new box, never configured CUPs, was browsing a
webpage, hit print without thinking I hadn't configured printers on this
box, and this PC used my network printer (on another PC) all by itself.

Stop cups-config-daemon by doing:
chkconfig cups-config-daemon off
service cups-config-daemon stop
The second line stops it, the first line sees that it does not start
again.

Documentation: Have you looked in: http://localhost:631
then: On Line Help.

I've done this 2 days ago (adding --level 2345 to be sure!)

BUT: still something is re-writing my cupsd.conf on my server and
clients are still unable to print.....

This re-writing is not done at boot time but at some times I cannot
determine.

I check the cron and anacron daemon, I check the crontab: nothing.

Who has invented something like and for what purpose; I feel to be under
windows when you cannot do anything because everything is hidden!!!

Has anyone suggested the following:-

service cups-config-daemon stop
chkconfig cups-config-daemon off

I always remove the daemon,known to cause havock on some systems

cups-config-daemon comes from the hal utilities package, I have found
it best to stop hal and cups config daemon and this usually stops most
problems.

No! This is not a solution: stopping hal will stop to much thing!

There a lack of information somewhere in cups and developpers should
tell where is the template for re-writing cups.conf and how to stop
it.

What is the meaning of a filefor configuration  with more than 800
lines if you cannot change anything in it because a devil (not a

I have an off the wall question for you. Do you have a /sys directory
