This may or may not help you. There are some crazy things happening to w10 with all these recent updates.
I have a Samsung laser printer and have always used the Samsung software to print. W10 was linked to that printer.
I noticed that under settings, then printers and scanners there is a box checked that allows Windows to manage my default printer.
Unchecking that box sorted my print problem out. (Mine was that it ignored printing in Landscape mode even if I highlighted that orientation.)
