The eSCL protocol needs AirPrint on the device. Would you confirm you can scan with xsnae "airscan:w0:EPSON ET-2710 Series" or simple-scan "airscan:w0:EPSON ET-2710 Series" Unfortunately, the vendor's implementation of WSD may offer only a limited number of resolutions. airscan cannot do anything about this; it can only work with what it is told by the device. With a USB connection, what do you get for lsusb -v | grep -A 3 bInterfaceClass.*7 ? -- Brian.
