Change the printer driver settings (Windows/macOS)

I am using the Windows driver. How can I change or save the 2-sided(Duplex) Print setting?

How can I know how many pages the printer has printed?

I'm using Windows®. I want to change the paper tray and paper size settings. Do I change these things on the printer front panel, or in the driver? And if I change the setting in the driver, will the printer front panel setting be used?

How can I activate/deactivate the Toner Save Mode?
