There is a directive
PageLogFormat 
for use in cupsd.conf. It uses a template defining the desired format for the
page_log entries (see the online help for details.

If this keyword is *not* present, the default format is used.
But, if the keyword is used without an argument, this means that *no* page log entries
are written, and an empty page_log file is created.
