Navigate to the 'Print' tab at the top left hand area of the map.
You will see a button titled 'Print'. Click this button.
Make sure you are zoomed to the area of the map you require a map of. You can also toggle the Map Scale dropdown area to better define the area. The red outline is what will be displayed in your map.
If you need to re-center the map, you can click and drag the red area, which is the area of the map that will be printed.
Once you have your desired map area, press `Print` and your map will begin to download. This can take a moment depending on the size of your map.
Once it finishes, you will be presented with an option to download your map.
