Hppsc750 (printer/scanner/copier) does not communicate with my Dell Dimension 4400.

1)right click the my computer icon
2)click properties and then click hardware n go to device manager.
3)uninstall all usb ports and then scan for hardware changes
4)ur pc will detect your printer and ask for printer drivers
5)re load drivers and your pc will communicate with your printer
6)for reloding install the cd follow the instructions on the screen and click next
7)restart when the printer is loded.connect the wires and cords properly
