I see are looking for steps to uninstall your HP Officejet 6500 and install with newer drivers. Try the following HP document: Uninstalling the Printer Software, that should clear out the software. You can select your Operating System and download software here: HP Officejet 6500 All-in-One Printer - E709a Drivers.
Since there are several 6500 series printers, if the above is not yours reply back with the model of printer you have.
