Argentina, Venezuela and Zimbabwe aren't in any way representative of the results of "printing money". They are much more complicated than that, and MMT actually has much more explanatory power to explain what went wrong (variously - huge supply shocks leading to massive unemployment, attempting to maintain a peg to a foreign currency, and having debt denominated in a foreign currency, etc.).
One of the leading MMT researchers, Prof. Bill Mitchell is especially interested in inflation, and they have actually generated a pretty strong theoretical framework for how it happens that again has better explanatory power than competing theories (i.e. Austrian economics that predicted hyperinflation due to QE, monetarism that can't explain why inflation is so sluggish with such low interest rates, etc.). He publishes a lot of info on this his blog nearly every weekday, it's definitely worth a read.
