The Olivetti Any Way and SImple Way are two printers with either WiFi or Bluetooth to enable you to wirelessly print photos without any sort of third-party add-on. The Any Way has a 2.4-inch LCD, prints 20ppm in black and white and 18ppm in color. A 10x15 takes 75 seconds, and has image improvement software to brush up your older photos. And of course, the optional Bluetooth and WiFi connectivity.
The Simple Way, a lower end printer, has the same 20ppm for b/w and 18 for color, but doesn't have the optional photo faxing. Oh, and Olivetti is only available in Europe, so tough titties to us in the US.
