Thank you for the reply, Abegail.

There appear to be only two options for invoices: "new" and "it looks like it is from 1987". I have been using the "new" one since I started using Quickbooks Online. It looks much like the version I had on the desktop.

Thus, using your steps and reverting back to the horrible looking 1987 ASCII art version does not solve the problem.

The browser's cache does not seem to be the problem, either. Surely I am not the only customer who had this happen. And how can I change the margins? The invoices end very close to the bottom of the page before a page break.

Let's try a different solution.
