I wonder whether the net backend is required. What happens if the
entry is commented out?

Scanning is taking place using the WSD (Web Services for Devices)
protocol. 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 ?
