I would like to install the chipless firmware on an Epson WF-7710

I normally use the printer through ethernet connection.

Can I hook up the USB to do the firmware, then return to ethernet connection, or do I need to keep the USB connection in place?

Do I need to disconnect ethernet connection to do the firmware update?

Thank you
