Why bother? The AirPrint technology built into the MFC-J5720DW printer can do that. Why can't CUPS send PDF down the wire to the printer, thereby avoiding all the driver-crap? You've just said "The AirPrint facility handles a PDF" (requoted above). Why not let it do so?
my guess is that airprint is a black box between the "air" (what ever it means) and the printer, like an ethernet card can be.
If you send ethernet signal through usb, the printer wont understand it. If it's so, the printer only understand pdf if used with airprint.
the other solution is having in the printer a linux box (invisible to user) having an airprint interface, an usb interface, etc, and then the usb may also understand pdf.
