The page_log file lists each page that is sent to a printer. Each line contains the following information:

printer user job-id date-time page-number num-copies job-billing
DeskJet root 2 [20/May/1999:19:21:05 +0000] 1 1 acme-123
DeskJet root 2 [20/May/1999:19:21:05 +0000] 2 1 acme-123

The printer field contains the name of the printer that printed the page. If you send a job to a printer class, this field will contain the name of the printer that was assigned the job.

The user field contains the name of the user (the IPP `requesting-user-name` attribute) that submitted this file for printing.

The job-id field contains the job number of the page being printed. Job numbers are reset to 1 whenever the spool directory (/var/spool/cups) is cleared, so don't depend on this number being unique!

The date-time field contains the date and time of when the page started printing. The format of this field is identical to the data-time field in the access_log file.

The page-number and num-pages fields contain the page number and number of copies being printed of that page. For printers that cannot produce copies on their own, the num-pages field will always be 1.

The job-billing field contains a copy of the `job-billing` attribute provided with the IPP `Create-Job` or `Print-Job` requests or "-" if none was provided.
