I don’t think this is necessarily a good explanation. Inflation doesn’t necessarily have anything to do with more money being printed. No money could be printed and inflation could still happen.

All inflation means is the average price of goods is rising. That could be because workers are unionizing leading to higher wages and capitalists decide to raise prices to keep profits similar, it could be because unemployment is down and a similar effect occurs, it could be because of supply line problems, capital strikes, a whole myriad of things.
