TrustedReviews have looked at the Lexmark Z1420 Wi-Fi Enabled Inkjet Printer

There's no doubt it can be useful to have a printer which doesn't need to be connected to a PC via a USB cable. If you already have a wireless network in your home or office, or if you're contemplating getting one later on, the Z1420 is an inexpensive printer to buy and run. It's also a very slow printer, particularly printing colour, and doesn't give the best print quality you can get, even at this low entry price.
