Take a look at https://wiki.debian.org/CUPSQuickPrintQueues The quick ref is to install avahi-utils and run avahi-browse -rt _ipp._tcp | grep URF If you get a line matching URF the printer supports the AirPrint service. Install cups and see if it works (which is all that I needed to do to get the printer working). If no, what does avahi-browse -rt _ipp._tcp and systemctl status avahi-daemon show you? Regards, Lee
