samba print server for windows network, cannot save printer setting
 

Hi,
I have set up a samba print server to share my samsung printer ML-2010(non-postscript).The print server is set up to accept raw print job and the printer driver is distributed to clients automatically(using [print$]). I have installed the windows driver into /usr/share/samba/drivers/w32x86 successfully but when i choose the driver then click ok(from windowsXP), i receive an error: "Printer setting can not be saved, access denied". Thus, although the driver is available on samba server (under /usr/share/samba/drivers/w32x86) it can not be distributed or used by any windows machine. Anyone have an idea what may be wrong?
Thanks in advance
