Dell XPS7100, Windows 7-64 operating system, Dell v515w all-in-one printer connected to Netgear 6250 router via the usb port. The computer will print documents to the printer as it is set up. If I try to access the printer via "Dell Printers" it is not recognized. The same is true if I try to use Microsoft Scanners and Printers. I have deleted/uninstalled the printer repeatedly and re-installed - still no luck. If I try to use the printer display it just returns a notice that it is downloading driver software, but it still doesn't work. What am I doing wrong and what do I need to do to correct it. Thank you, Richard
