Thanks for getting back to us, @accounts501. We can perform some troubleshooting steps to get this back to normal. 

There are times that the browser is full of frequent access web pages. When this gets outdated, it can cause an issue with your QuickBooks performance. 

To verify this, let access your account via a private window (incognito). Then follow the steps, I've shared above on how to clear the text in the Add footer text column.

Once done, you can now create an invoice and download or print them to verify if the text will show. If it works, you’ll have to go back to your main browser and clear its cache. Clearing them fixes certain matters, like loading or formatting issues on sites, and helps increase the performance of your computer. You can also use a different browser if the issue persists.

Also, you can add a screenshot for me to visualize and further check on it for you. I appreciate any extra information you can give, and it will help us isolate the issue and provide the best solution. 

For future reference, read through this article should you need to print multiple invoices in batches: Email or print multiple invoices and sales forms.

Give this a try, and let me know how it goes by leaving a comment below. I'm only a post away if you have any follow-up questions. Take care, @accounts501.
