Thank you for your data, Chris. The lack of an output for _uscan._tcp indicates to me that the device does not support the escl protocol. This means that, unfortunately, sane-airscan is not available for you to to use. I will, of course, defer to more expert opinion than mine.
The _ipp._tcp output indicates the device supports AirPrint. It would seem that the generalisation that *all* AirPrint devices also support the escl protocol needs revising. -- Brian.
