No. (I think you meant PDF). The PDL of choice for AirPrint capable devices is PDF. A PDF document sent to an Airprint capable printer is converted to BUL (the Brother Unknown Language) as it would be if it was processed on a workstation by CUPS. Note that this is a conversion, not an interpretation. An interpreter produces a raster image and this happens later when the RIP deals with BUL. > > Whether the printer > > handles direct PDF printing is questionable.

The MFC-J5720DW doesn't have a PDF interpreter. Hence the silence.
