Query: Warning...Warning...Warning

Much to my chagrin, my new HP s7320n desktop computer began locking up as soon as I connected this printer to it. After two working days of diagnostics, restarts, and even taking the computer back to where I bought it for an exchange, an arcane service bulletin said that this printer is not compatible with this computer.A sign of how far down HP has slid...an HP printer (which is otherwise a pretty good printer) that is not compatible with an HP computer.Seriously.So, before you buy one of these, make sure it will work with your HP computer...
