Hi computeir, sorry to hear that you are having issues with getting your printer installed on to your computer. If you are connecting the printer to the computer with a usb cable, please remove it from the printer and the computer and set it aside. Please click the link I have provided for the HP Printer Install Wizard for Windows.
The installation will prompt you as to when to connect the usb cable. If you are still having issues, please feel free to write back.
Thank you.
