It's the loan creation that creates the money that hits the economy.
yes this is exactly what everyone means when they say the Fed, in effect, prints money.
Not from what I've seen. From what I see, many people tend think the Fed just puts cash into the economy - it does not. People tend not to distinguish reserves from cash from bank liabilities from collateral.
Money is created when money/money-like financial assets are added to the total pool of assets in the economy without the same number of assets being removed. The Fed's operations involve an exchange. A private bank, however, creates a new deposits without exchanging anything in return every time it makes a loan. If I go to Bank of America and take out a loan, Bank of America just changes the number in my deposit account with them; it doesn't subtract anything from anyone; the bank creates an asset (my future cash flow to the bank), a liability on me (my promise to make good on my debt), and another liability on the bank (the deposit account). The actual money creation is done by private banks, not the Fed.
