Question about HP M477fnw Color LaserJet Pro

The equivalent model with duplex printing was the HP M477fdw and now its successor, the HP M479fdw.
f is for fax, d for duplex, w for wireless. So: If duplex is a criterion, be sure to look for the "d" in the name!

For information: d stands for duplex print, f stands for fax (only the versions with fax have a duplex scanning unit, otherwise only one-sided scanning).

So does this MFP have duplex or not?

I bought the M479fnw in anticipation, believing that it could automatically duplex print and automatically duplex scan. Now I realise that it can only do manual duplex printing.
Or have I overlooked a setting?

Which of the M479 series can do both automatically?

Thanks for the info!
