Print the map
It's possible to print the map using the browser built-in print dialog. However, browsers sometimes behave rather unpredictable when printing the map. Typically, the part of the map that is actually printed is shifted from the map shown in the browser. Unfortunately, there is no better solution than moving the map until it works out or printing a screenshot.
Creating a screenshot of the map can be done easily, depending on your operating system.
For Mac and Linux users it's easy, just press Shift+PrtScn, select the part of the screen and save it as file. For some reason I cannot understand Microsoft makes taking screenshots so much more complicated. I recommend to run the Snipping Tool (installed on all Windows from Windows 7 and up).
