Unfortunately, not all languages/systems have an efficient and useful debugger. This becomes especially true when multiple stacks are involved. But the print statement remains possible across almost all tools, technologies and systems |

Another use case for printf debugging is occasional or transient issues where there is a bug, but it only presents in an aggregate of many runs (or a lot of runtime).
I debug scientific simulations in this way with printf's, because I need to look across 100 log files to find 2 or 3 instances of a bug.
Then I can reproduce it and zoom in on the exact problem with either more logging or a debugger.
