I'm using Windows Vista Ultimate Black Edition computer (which is a custom OS). I'm also using a Windows XP computer and the printer that I'm using right now is an HP Photosmart C2580 All-In-One Printer. It is connected to the XP computer right now. When I set up my new Vista computer which had Home Basic at irst, I tried to get the printer over at the XP computer shared on this one and it worked. Then, we installed new Windows Vista Ultimate Black Edition and now it won't detect the printer at all. We tried sharing it with the right computer and printer name on the other computer but no luck. Is it because there are no printer drivers for this custom edition for Windows Vista? We tried to install all the drivers from the HP site but nothing work. How come the Vista Black Edition computer can't detect the printer on the XP computer?
