We bought a new computer and are trying to install our HP Officejet 4200 all in one series printer on it. The computer is a gateway and shows the driver for the 4200 series after a driver update. It then asks for the port...printer port, serial, and or local. I can also create a port. All I know is that there is a USB connection from printer to computer. Am I supposed to plug the USB into a specific port? We are running Windows 7 if that helps. As always, thank you for the help!
