Often, the best option to fix these problems would be to reformat your computer and reinstall your OS, but since most of us don't plan on ever taking this drastic measure, we don't obtain a recovery disc or thumb drive. In other cases, your Mac can be experiencing some major malfunctions: constant crashing, locked controls, slow boot times, missing files, etc. At one point, I realized that there were plenty of files on my Mac that I didn't need any more, but too many to delete individually.

And it’s a handy one liner that may come in handy when troubleshooting. I just wanted to document this new option because it hasn’t really been documented anywhere that I can tell.

With macOS Catalina, Apple silently introduced a new option in their printtool command line tool to reset the printing system. Today, the logic and script still works, but it sure would be nice if it wasn’t needed in the first place. I shared the script on JamfNation at the time. Back in 2015, I set out to find a way to do this programmatically so that it could be scripted.

If you’re reading this blog post you’re probably interested in automating that task. For example in macOS Mojave, you could go through System Preferences > Printers & Scanners and right-click (cmd + click) the list of printers and select “ Reset printing system…” from the contextual menu. Prior to macOS Catalina, one way to reset the printing system was through the GUI. Sometimes you need to reset your printing system to resolve some weird issues with one or more of your print queues.
