Can you explain to me what does AirPrint has to do with driverless printing ? Can you explain to me if AirPrint allow my printer automatic discovery ? IPP ?

I already know that you'll keep on and possibly next time ask me what page of the specifications. I'll save some hassle and write it now. Page 16 for the scanner specifications -- All scanners and all eSCL clients MUST support at least two output data formats: JPEG and PDF.
