Most debuggers have conditional breakpoints and print-breakpoints, no need to step through line by line manually. If something strange happens just right-click and insert a print as the program is running.

With print-debugging if you find a bug you have to stop your app, insert print lines, recompile, redeploy, relaunch, click through your app to reach buggy location and then scan through log. This really feels like stone-age once you've ever used a IDE.
