I dont know if you have it fixed Suzanne, but pc's are very annoying lol........and all i can say is they drop thingsthat have worked a few minutes before, and by the sounds of your problems it seems that the pc may have dropped the printer and you may have to re-instal the drivers for it, this means uninstalling the printer from the actual Control Panel, under instal and remove hardware, and then reinstall it all with your printers disc and go onto HP website for any updates on them drivers that you may need.....that should sort it, it also depends on whether you have Xp or Vista as the add and remove hardware maybe in different places but i know about both of them operating systems so if you still cannot fix, give us a shout!!! sorry is im teaching you something you already know or have done, just trying to help, my ethernet (epson) and connected Epson are buggers, hubby has HP's

hope ive helped, if not/................ignore me LOL!!!
