I remember when I updated to Win10 on both my PC's, it had an issue with the printer drivers. They will still work with the basic printer driver, well for most features. But even after installing the correct printer driver it didnt work until I found I needed to delete the unknown device in the printer section.
An easy way to see if its the printer is to go to windows update and see if its failing to download a printer driver.
Have a look in the device manager and see if there is anything marked (!) . let us know what sub menu it is in.
