I have an HP computer with XP home. I have an HP F2110 all in one printer. Every so often I see on my computer SCREEN the printer being installed like it is a new piece of hardware. When this happens I look in the control panel at the printers and there will be a printer icon but it will printer #2. I have seen as many as 5 printers. I delete all of the printers but one. I go into services to HP device discovery and stop this service. Everything will be alright for a few days. Then the process starts again. I look at the services and HP device discovery is started again. Does anyone know how to CORRECT this problem?HP finally come out with a patch (fix) for this problem. I FOUND it on their website. I am SURE glad because I have had this problem for 2 years.Chiming in a bit late, but glad you found a solution. I had the same thing with my HP, except I have 4 printers. It kept dupliucating them all on boot or when one was unplugged and PLUGGED back in. Annoying that was.
