Setup the wireless through the front panel in about two minutes --- automatically detected via Windows and Linux. The bundled driver allows for wireless scanning, scan/print via an Android phone, and so on. Full-featured. The 250-sheet paper tray is flimsy, but I'm glad the printer holds that much. The plastic used throughout the printer is pretty flimsy, but it's a $100 multi-function device. It will do two-sided scanning and two-sided printing... The printer will accept the extra high-capacity ink cartridges -- not all of the epsons will. As a consumer device, having just had it for a month or so, I'm plenty happy with it. Keith
