I need to purchase a couple of printers to use at home. The first will be an HP L7780 for general purpose use by all the family also this will connect directly to the home network, the other will be a dedicated photo printer, I have been considering the new Epson R1900 Stylus Photo as this fulfills my need for A3 and CD/DVD Printing also will this work on the network if connected to the USB port on my Airport Extreme. Thanks in advance
