I have linked the statement that money printing does not lead to inflation to a somewhat deeper analysis on my blog.
In a world of free capital flows around the world, money created by central banks can flow freely to wherever it generates the highest returns. This is why we see asset price inflation in weird corners of the world. But for consumer proce inflation to rise the money has to end up in the real economy as banks lend the money to households and businesses. And at near zero or even negative interest rates lending is so I profitable that banks curb lending. The BIS has a series off papers that show that empirically and it is the biggest problem for stimulating the real economy with monetary policy today. It is literally Key es problem of pushing in a string.

As an aside I am German and my parents fled from Hungary. These two countries had the highest hyperinflation ever recorded and I remember the high inflation of the late 1970s and early 1980s even though I was a child then.
Emerging markets often experience high and hyperinflation as a result of money printing but for then there are two structural differences: (I) a lot of their debt is denominated in hard currency meaning a depreciating home currency creates a debt spiral and (ii) the flows in and out of the home currency are overwhelmed by investors from developed and foreign markets. These investors flee if they lose trust thus creating a deadly depreciation spiral and thus a spike in inflation (see Turkey for example or all the Latin American countries in the 1980s and 1990s). But this is fundamentally different from major economies in the developed world.
