Thanks for taking the time to share your concern and the workaround you found here in the Community, Ted. Let's perform some troubleshooting steps together to isolate this issue.

A cache-related problem could be causing some pages in QuickBooks Online not to load properly. To address this, I recommend opening your QuickBooks Online account in a private browser to allow QuickBooks to start on a clean slate.

Here are some keyboard shortcuts you can use:

• Google Chrome: Ctrl + Shift + N
• Safari 11 or newer: ⌘ + Shift + N
• Mozilla Firefox: Ctrl + Shift + P
• Microsoft Edge: Ctrl + Shift + N

Afterwards, print a dummy invoice. If everything works smoothly, I suggest going back to your regular browser to clear its cache. Alternatively, you can also use other supported browsers.

Once the issue is resolved, here's a guide on receiving your customers' payments: Record invoice payments in QuickBooks Online.

Let me know how the troubleshooting goes in the comments below, Ted. I'll be around to provide further assistance.
