I cannot get HP8710 printer to download on my laptop.

Uninstall the previous printer driver from the root level. Open Programs and Features, Select your HP Printer from the list  and Select Uninstall
Open Devices and printers, search for your HP printer from the list, right-click on it and choose `Delete’ or `Remove Device’
Now, Press and hold together the “Windows key + R” key.
Type printui.exe /s  in the command box and hit Enter (there is a space in between “printui.exe” and “/s”)
Click on the “Drivers” tab, Look for HP Printer driver. If you see it Click on it and click Remove at the bottom, Select Ok, Select Apply and Ok on the Print Server Properties windows
Now download the latest version of HP officejet pro 8710 from the link provided below and follow the onscreen instructions to install the software. Connect the USB only when prompt by the installer.
