DX8400 Not Working With Windows 7?

I have tried my ultimate hardest to try and get this printer working with Windows 7, I downloaded the current drivers, I did the CD install and everyhting and nothing is working, however I think I came across the solution that it wasn't any of that, that was the problem. When I connect the printer cable, it makes the sound, but nothing actually pops up, i'm on a laptop, and the USB ports work with everything but the printer, any reason as to why this is? Thanks.
