cups installation: Unable to read configuration file '/etc/cups/cupsd.conf' - exiting

[iks_kzm <krupa@alpha.sggw.waw.pl>]

I had problem with cups: 
--
During the configuration (http://localhost:631/   as root)
I configured the printer: e.g. 1200 dpi, ...).
When I print something from  root account it seems that the cups
works OK and configuration of the printer is OK.

But when I use the printer from NON-root account it seems that
the configuration of the printer is NOT OK.
E.g. when I print some picture (region filled with gray colour)
it is printed as black but from the root account it is printed OK.
--

So using dselect I uninstalled cupsys, cupsys-client and cupsys-bsd, 
then tried to install again the above packages but due to security
problem dselect could not find these packages 
so I chose 'update date base...' and dselect started to install these
packages from:
http://security.debian.org stable/updates/main ...

During the installation I got the following message:

"cupsd: Unable to read configuration file '/etc/cups/cupsd.conf' -
exiting"

and there is no file cupsd.conf in /etc/cups/.


Then when I connect (using mozilla) to
http://localhost:631/

and then try to choose "Do Administration Tasks" or "Printers"
I got :
"Alert! The connection was refused when attempting to contact
localhost:631."

I am NOT asked for neither root nor any other  password.

What am I doing wrong?

Could someone please help?
