This may not be relevant, but, for what it's worth.
Since the very first build of Windows 10, I have had some small problems through the "devices and Printers" - Add a printer.
The program could see, and accepted my two printers, which were on my Lan, but they did not appear on the "Added" page, nor could I print a test paper.
But, oddly, and by accident, I had a couple of documents which I wanted to print (from WordPad). So I selected "print and, to my surprise, both printers were listed. I selected my favoured printer, and a pop up came saying it needed to download drivers. I accepted this - Voila - The printer is now fully functional!
