It is so easy to find just plain wrong information on the internet these days. The problem is people don't know what they can and cannot trust, so it continues to perpetuate itself even amongst more intelligent people.
The government can not print money, every dollar printed has to be borrowed into existence via debt. If the government could print, then there'd be no need for tax. Watch the Moving forward movie for more revelations.
Our government can print, the Treasury has the legal ability to do so at any time. The Federal Reserve however owns the Federal Reserve Notes (aka the 'dollar'), and they own the US Government accordingly.
Our government would both print and tax, as many other governments throughout history with an abusive printing press have done. Just because a government has a printing press, they never stop taxing.
Governments print and tax because they can, it slows down the rate of inflationary pressure that printing would generate if that's all you did. As it is, they like to keep inflation hidden as much as possible by keeping it moderately low so you don't notice it year to year. The whole point is to boil the frog without the frog jumping out of the pot.
