You're technically right that germany doesn't print euros, the ECB does. But your conclusion is still wrong: germany isn’t remotely close to bankruptcy, and equating its situation with Argentina or Greece misunderstands both monetary sovereignty and how the Eurozone functions. As to how freely a country, especially germany, can print money: German government bonds are one of the most sought after, because risk free bonds of all. If it really wants, it can sell as many as it wants; because it has such a strong economic power behind it.
