[FIXED] Freezing Printer Problems: Resetting Mac-Os’s Printing System

Printers have become an essential piece of hardware for both businesses and individuals. Like any machine, printers are subject to both software and hardware Printer Problem. If you are currently yelling at your printer after failing to print your assignment on a Mac, you might want to consider resetting your Mac-Os printing system.

When the printer and scanner preference pane winds up empty on your Mac, you could experience particularly long delays on the order of minutes. To sort this out, you might want to reset your Mac-Os printing system.

But before the step-by-step reset process, trying one of these initial steps can easily get things back on track for your Mac printer:


  • Ensure that you have connected the printer properly to the Mac or the very network used by the Mac
  • Get the printer driver software updated
  • Go to your Mac and delete the printer before re-adding it at the Printers & Scanners preference pane
  • Also, restarting the printer and/or Wi-Fi router might resolve the problem

However, these simple fixes are sometimes not enough, and when they fail, you can then bring out heavy-duty tools for a full-swing reset.

macOS has a hidden command that is designed to reset Mac’s printing system. Using it clears out your device list for printing, scanning, or faxing from the Printers & Scanners preference pane as well as doing a series of behind-the-scene functionalities.

The hidden command functions as a last resort reset feature, and that is why it does not feature in any of Mac’s standard menu for resetting the printing system. This makes it harder to find accidently, but once you know it, you can use it easily.
