Hp Deskjet 5650 with fault and missing usb cable (Southgate N14)

Hi, This printer works, but sometimes creases the paper when fed through. It has been sitting around unused for a few years, so maybe just needs use, or a simple problem to fix. Also it is missing the cable that goes from the back of the printer to the usb port of the computer. On the photo it is the connection above the mains and below the pink connector. It will need printer cartridges.
