page_log history

[Maelvon]

Hello,

I have cups, and it seems it keep in var/log/cups/page_log etc only one 
month of printed jobs ! I've think it keep more than one month in the 
logs. I've installed it in june, and have only the september jobs in the 
logs... How can I configure the log history length ?

---------------------
# ls -s -h
total 4,9M
104K access_log    4,0K cupsd        968K error_log.3   16K page_log.3
  48K access_log.1  4,0K cups-lpd     968K error_log.4  8,0K page_log.4
  24K access_log.2  1,2M error_log     16K page_log
  36K access_log.3  900K error_log.1   12K page_log.1
  80K access_log.4  656K error_log.2   12K page_log.2

Thanks,
