Have in mind that in particular with "LogLevel debug" and
even more with "LogLevel debug2" the /var/log/cups/error_log
file could grow fast to enormous size in particular because
some printer drivers may write zillions of driver internal
debug messages to the /var/log/cups/error_log file.

See "man 7 filter" or
http://cups.org/documentation.php/doc-1.7/man-filter.html

LOG MESSAGES

   Messages sent to stderr are generally logged to
   printer-state-message attribute and the current ErrorLog.
   Each line begins with a standard prefix:

   ...

   PAGE: page-number #-copies
   PAGE: total #-pages
     Adds an entry to the current PageLog. The first form
     adds #-copies to the job-media-sheets-completed attribute.
     The second form sets the job-media-sheets-com-pleted
     attribute to #-pages.
-------------------------------------------------------------------
I.e. send a message with a 'PAGE:' prefix to stderr
to get an entry in /var/log/cups/page_log and see
http://cups.org/documentation.php/doc-1.7/ref-page_log.html
for the format of PageLog entries (e.g. for CUPS 1.7).
