/var/log/cups/page_log file not getting updated

Hello everyone, I am using suse 10.1 and is trying to use cupsaddsmb to install printer drivers in the print$ samba share so that windows clients can do automatic download of drivers and printing can be accounted. I could manage to install drivers using cupsaddsmb and clients could install the printer. But when i print from a windows xp client, the /var/log/cups/page_log is not getting updated at all though the jobs gets printed properly.. Could anybody give me some hints so that I can log the number of pages printed by windows clients. I am using cups-windows-6.0-1.i386.rpm. Regards Vinayan K P
