Normally print isn’t a debug message function, people just use it like that. (it normally works on non debug builds)
If your console app is writing output to any device, it must, for instance, handle errors gracefully.
That means, at least in Rust, write! rather than print!.
From the docs: "Use println! only for the primary output of your program. Use eprintln! instead to print error and progress messages."
I personally find myself using print debugging as a last resort when the debugger doesn't suffice.
