It works fine for me? Not wishing to teach granny to suck eggs but here is how I did it --
Launch EpsonNet Config
Your printer should appear in the list, highlight it and then select Configuration at the top.
It should then show a screen saying something like 'Retrieving settings' then a screen...
Anyone know how to set the IP to a static rather than DHCP on this printer? Been through the setup a few times but it only asks me which router to connect to and the passphrase then off it goes and assigns a DHCP IP! Bit daft for a network printer!!
