Have you downloaded the latest drivers from HP's site? I selected C6340 in that as you didn't specify the model you have

I have an HP Photosmart C6350. It wouldn't make sense to downlaod it again because doesnt it already come installed on your computer? It worked once and that's why I don't understand why it won't work again.

Sometimes the drivers provided with OS are old, especially if the product you have is new. See this, it's a firmware update that solves the issue regarding to network printing. Also see other downloads
