Network Goodness

I've got 2 Apple Airport Express units so that I can wirelessly connect to my ADSL line which is downstairs AND have the ability to print to me USB printer upstairs.
I also have a Ethernet Laser Printer which is currently plugged into the ADSL router and all works fine.

I've just tried plugging it into the 2nd A.E. and what do ya know. It bloomin' well works!!! I'd been told by the muppets on the front desk at Solutions in Brighton that this would not work. "The Airport Express isn't designed to extend your wired network..."

Now I can get that laser up stairs with the other printer :)
