*How* did you install that driver? And the printer you own is in
fact a PostScript-enabled modell? (Sorry, I don't know by heart
if that 2100M defaults to include PS, or if PS is only an upgrade
option....)

If you installed it as a local client driver, you have to use
"use client driver = yes" in smb.conf (this is not the recommended
setting, but works also....).

A locally installed driver (for a shared printer) on the client
can be more exposed with this commandline (in a Samba host shell),
even if the test page isn't printing:

   rpcclient -Uwindowsuser%windowspassword -c "enumdrivers 3" windowshostname

This command shows up pretty much the same info as a printed
testpage would do....

If you installed it via "Point'n'Print", you should be able to
use that command in a Samba host shell:

   rpcclient -Uroot%smbpasswd-of-root -c "enumdrivers 3" localhost

The operating system? Linux? Which distro? Who built the Samba
packages? Is CUPS support compiled into the Samba binaries?

> about the driver becasue I can't print the test page. 

See above.

Is this the same smb.conf you inherited from your previous Samba
installation?

Change that to

         security = user

as the Samba HOWTO Collections suggests. (Don't forget to set
Samba passwords with "smbpasswd -a root" and "smbpasswd -a
username"....)

So your old Samba with the same smb.conf setup did work with
CUPS-1.1.20 ??

This setting doesn't work for any other host as a client.
(It works for Samba, since smbd transmits the file to
cupsd from localhost...).

You should either comment the line out (in which case
cupsd will default to use the hostname for "ServerName",
or use "ServerName <your host's IP address>" or explicitely
go for "ServerName <your hostname>".....

"LogLevel debug2" will drown you in error messages. Considering
that you have limited the error_log file size to 1 MByte, this
will effectively prevent you from ever finding anything useful
in the log. 1 MByte of debug2 output fills the file in seconds
before it log-rotates.

Better use

   MaxLogSize 10m
   LogLevel debug

and have all the relevant info at your fingertips. In case there
is really a severe problem, you can always go for "debug2" and
50 MByte for a limited period of troubleshooting.

What do you see in the "/var/cups/log/error_log" as noted when
the job arrives at CUPS? Look for a line containing

    "print_job: auto-typing file..."

and the following

    "print_job: request file type is"

What is it?

Also look/grep in the error_log for all occurances of lines
containing

    "start_process("/usr/lib/cups/filter/"

and

    "Started filter /usr/lib/cups/filter/"

Do you see any errors here?

What are the complete lines containing

    "StartJob: envp["

and

    "StartJob: argv ="

??

I hope you take note of all these hints, even if the first one
may already solve your problem. They'll help you troubleshoot
future difficulties with CUPS and CUPS/Samba printing....
