Not to nit-pick, but it's printing too much money that causes high inflation. As the efficiency of producing goods and services increases due to technological advances and growing populations, we end up with more "stuff" in circulation. Without a gradual increase in the overall money supply, we would end up with deflation.
Also, in terms of monetary policy, the old adage is that it's easier to pull on a rope than push on one, so it's easier to manage just a little inflation than a little deflation, so central banks aim for a low rate of inflation.
