Can you print economic output though? Printing dollars only works when there are things to buy and sell. More money and less things to use it on only makes the money less useful (inflation). Usually the economy can absorb that extra supply pretty well to the point of being insignificant, but that doesn't work when you just stop said economy. Also, how do you think we will be able to support and help those more vulnerable if we don't have any economic output? Will printing money make supplies appear from nowhere?
