I just tested installing an AirPrint capable printer (a Brother MFC printer in my case) on an Ubuntu based
Linux installation (Peppermint 9).
The printer’s PPD was generated by the driverless utility which is part of the cups-filters package.
The generated PPD is correct and reflects – as far as I can see – all features of the printer correctly,
including the duplex facility.

And, using the cups web interface (or the lpadmin utility, if you prefer command line utilities) allows
modifying the duplex default setting (which is preset to off).

But I saw – on this Linux distribution – that the printing dialogue (when printing from an application,
e.g. the firefox web browser) does not allow modifying the default settings such as color/bw or duplex etc.

So you presumably need to modify the default settings of your printer,
