Oops! Sorry about that. The page I liked to is definitely where you get to by following links from Epson's support pages for your printer but it seems to assume that the printer has an LCD display on it (which, looking at pictures of the printer, I now see that it doesn't).
Try downloading 'EpsonNet Config' from here:
ftp://download.epson-europe.com/pub/download/3779/epson377972eu.exe
(As that link is 'ftp', and not 'http', you'll probably need to copy and paste it into your browser's address bar. When you've downloaded the file, double-click on it to run it). That looks like the set-up utility that you need.
