Need more details. Did it work before? Is it seen by the computer at all? Generally the procedure to get these installed is to install the drivers for the printer first and only connect the printer once that is done and you are prompted. If you try to connect printer then do the drivers you can add up with a virtual USB port that needs a bit of work to clear before the printer can work.
-yes its work before
-can't detect between computer and printer at all.
Try a different USB cable and also install it on another system and see if it's seen there.
Check Device Manager and see if it's seen there as some type of generic USB device or there with an error code also. If it's there, delete it, delete any HP software in the Programs listing and re-run the setup again.
