The FED absolutely CAN print more money when they need to. But if they print just a little too much of it, inflation will grow, cash will be watered down, and ultimately the whole USD money system will fail. And, if they print it, why not see to it that the US government hands it out to the American public, so that people can prepare for the demise of their currency? Of course, all but a few of the people are too dumb to do this.
