Epson recently released "Epson Stylus Pro 4880, 7880 and 9880 Series Ethernet Firmware Update v1.03".
The only thing they say is "This firmware update improves Ethernet functionality."
Generally I jump on all updates quickly, but I am hesitating because a.) my Ethernet connection to the 4880 works fine; b.) I can't imagine what additional Ethernet functionality there might be; c.) failed firmware upgrades are nasty, and if not necessary are best avoided.
Does anyone know what this one is all about?
