In such a case you go to the makers site (that's dell.com) and see if they have driver for your version (32 or 64) of Windows 10. If you can't find it, contact their customer service to get a confirmation that it doesn't work or possibly a work around.
If no luck, your options are simple: either another printer (that has Windows 10 drivers) or another OS (that has a driver for this printer), such as the one you upgraded from.
