I appreciate the steps you've performed, @osfocory17.
I understand that turning off the double-sided when printing is essential to your business. Let me provide some details to help you with this matter.
Since all the steps you've performed didn't work, I suggest utilizing a third-party app that can connect to QBDT Mac.
I will guide you to our QuickBooks Desktop App Store, where you can select the perfect third-party application.
Proceed with the following steps:
- Go to the QuickBooks App Store.
- From the QuickBooks Compatibility section, choose the QuickBooks Desktop version you're using.
- Type in the clue word of the specific app you're looking for in the Search field and click the magnifying glass to search.
- Install the 3rd party apps and follow the on-screen instructions.
Moreover, I'm adding this article for your reference in troubleshooting problems when printing: Troubleshoot printing in QuickBooks Desktop for Mac.
