[Printing-user-general] Log with User-Page counter

Hi,
im Working in a small Pc-pool with 58 Linux-Machines. I've installed Suse 10.0
with Cups 1.1 and run the Cups-Server on one specific Machine because i want to
find out how many pages is each user printing.
Now I found out that kjobviewer lists all print-jobs with all needed
informations, but separately.

My Question: Where does kjobviewer get his information from and is there any
other possibility to view them?!

The Cups-Log files arent any help and kjobviewer doesent get its information
from theese files.

thanks for help
Aleksander
