There are a couple of features that are relevant to your scenario.
The first is custom map styles. You can customize the look and feel of the map easily with this API and create a map style that will have high contrast and print well in Black and White. See this sample for documentation.

There is also an app available to make creating your custom map style easy.

The new feature you should be aware of is XAML Islands. Starting with the October update of Windows which should be available shortly, you can embed any UWP control in desktop WPF apps, including the UWP map control. There should be a community toolkit update
shortly to make this even easier.
