Hello, @LighthousePublications.

The QuickBooks PDF & Print Repair Tool is designed to resolve any issues you encounter while printing, saving, and sending your forms and checks through QuickBooks.  Let's first make sure that your QuickBooks software and the Adobe Reader/Acrobat is updated to the latest version. 

Here's how to update QuickBooks:

1. Choose Help at the top menu bar.
2. Select Update QuickBooks.
3. Click the Update Now button.
4. Mark the tickbox next to Reset Update.
5. Hit Get Updates.

On the other hand, here's how to install Adobe Reader and Acrobat updates from Adobe Updater:

1. Launch Adobe Reader or Acrobat.
2. Choose Help.
3. Click Check for Updates.
4. Follow the steps in the Updater window to download and install the latest updates.

Once completed, let's restart your device to ensure that all components are updated. You can try to access QuickBooks again and view your invoices to print list.

Keep me posted if you have other questions about printing your sales forms and checks in QuickBooks.
