If you have upgraded your windows from windows 7 or 8 to 10 and your HP 6520 printer has stopped working, it means you have to uninstall the older driver and install the newer windows 10 version drivers on that. Now you can easily download drivers for windows 10 as well.
We have added HP 6520 windows 10 drivers into above download list. On November 17th, 2022 I have updated the Windows 11, Server 2022 and Mac 13.x Ventura drivers. You can download this printer driver directly from HP 6520 official download page.
