Adding this option will add Quality dialog which can be used to set your printing quality (in Windows, you will find this as Best, Normal, and Fast Draft). I set the default to Economy, so my ink will not be wasted too much for something that doesn't need to be printed at best quality.
Please note that you must remove your printer instance and re-add your printer to the system via CUPS's web administration interface before you can get this options.
