I am using Vista Home Premier and my dell All In One 948 printer is connected to my home network. Other computers in the network have no problem printing and scanning wirelessly. The printer installs a program called "Dell All-In-One Center - AIO printer 948 on my desktop. When I try to open the program, it says "The Dell AIO Printer 948 printer driver is not installed. Please reinstall your printer driver." I tried to uninstall it and reinstall it few times, but the problem persist. I even tried to use the USB cable to connect my laptop and the printer by using all 3 different ports. My computer cannot recognize the printer. I contacted Dell two times and was told to reinstall my OS. I was able to print and scan until I contacted Dell few days ago for an issue that some of the buttons were grayed out when I open the all in one center.
