I've just bought myself an Epson WF-3520 as a replacement for my old and now defunct Lexmark.
It does WiFi or USB connections plus scanning/faxing and will print from my wife's Ipad or my Iphone. You can also email it (it has its own email address via the Epson connect system) and it will print emails direct.
I thought it excellent value at £99 delivered, via Ama$on.
