Dear friend Karx asked me to try to print something and then give the differences in the three files in /var/log/cups. I tried to print one page from Libreoffice Writer and here is the result of running diff for the old and new versions of the three files for the three files. For access_log the difference is: 186,195d185 < localhost - - [19/Aug/2020:20:10:02 +0530] "POST /printers/HP-LaserJet-1020 HTTP/1.1" 200 215 Create-Job successful-ok < localhost - - [19/Aug/2020:20:10:02 +0530] "POST /printers/HP-LaserJet-1020 HTTP/1.1" 200 29704 Send-Document successful-ok < localhost - - [19/Aug/2020:20:10:24 +0530] "POST /jobs/ HTTP/1.1" 200 151 Cancel-Job client-error-not-found < localhost - - [19/Aug/2020:20:10:24 +0530] "POST /jobs/ HTTP/1.1" 200 151 Cancel-Job client-error-not-found < localhost - - [19/Aug/2020:20:10:24 +0530] "POST /jobs/ HTTP/1.1" 200 151 Cancel-Job client-error-not-found < localhost - - [19/Aug/2020:20:10:24 +0530] "POST /jobs/ HTTP/1.1" 200 151 Cancel-Job client-error-not-found < localhost - - [19/Aug/2020:20:10:24 +0530] "POST /jobs/ HTTP/1.1" 200 151 Cancel-Job client-error-not-found < localhost - - [19/Aug/2020:20:10:24 +0530] "POST /jobs/ HTTP/1.1" 200 151 Cancel-Job client-error-not-found < localhost - - [19/Aug/2020:20:10:24 +0530] "POST /jobs/ HTTP/1.1" 200 151 Cancel-Job client-error-not-found < localhost - - [19/Aug/2020:20:10:24 +0530] "POST /jobs/ HTTP/1.1" 200 151 Cancel-Job client-error-not-found ----------------------------------------------------------------------------------------------- error_log -- no difference ------------------------------------------------------------------------------------------------------ page_log -- no difference
