I am using CUPS 1.6.1.
I have a problem with printing the pages with one side only. Default option is "one-sided", as in the CUPS web interface configuration. But when I do the printing, it prints out "two-sided-long-edge" result.
I want to configure it manually. Where is the exact configuration file location? Whenever I make the changes from the CUPS web interface for default options, the /etc/cups/printers.conf time is modified, but content is not changed. But in the web interface, the default option is changed. Which file is the default options configuration?
