Where is the printer default option configuration file?

Question

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?

Answer 1

The setting is edited in the PPD file: /etc/cups/ppd/foo.ppd where foo is the printer name.

The normal way to modify these settings from the command line is the lpoptions command. It changes the system settings if executed as root, and the per-user settings (stored in ~/.cups/lpoptions) otherwise.
