It's the chain button next to the printer button just to the left of the map. It's... right there. What would you prefer they do to make it easier for you?

[EDIT] Oh, looks like I don't have the new version yet. Oops. Thanks for the correction.

No, it is not. The new maps does not have a print button:

Unfortunately you are looking at Classic Maps. Classic Maps was perfectly usable, I agree.
