• The U.S. Federal Reserve controls the supply of money in the U.S., and when it expands that supply it is often described as "printing money."
• The job of actually printing currency bills belongs to the Treasury Department's Bureau of Engraving and Printing, but the Fed determines exactly how many new bills are printed each year.
• When it is said that the Fed is "printing money," the reference is really to the central bank increasing the money supply in the system, such as through quantitative easing (QE), an asset-purchase program.
