Photosmart 1115 will not connect with a USB port

Trying to install an HP photosmart 1115 to a Dell laptop. There is only a USB connection cord. I'm not sure where the original software, manuals, or LPT1 connection cable is. I am trying to help a friend. The software download was successful, and the printer appears in the printer file, however, everytime we try to print a test page, we get an error message that the printer connection could not be established. Not sure how to resolve since we followed both written directions and tutorials from the HP support site. Any other thoughts?
