Is anyone having issues with batch printing of invoices. I am getting a timed out error HTTP 504

Hi audreypartidge6,

Welcome to the Intuit Community! You've reached the right place for help. Don't worry, I'm here to get to the bottom of this.  

The 504 error is an HTTP status code means that one server did not receive a timely response from another server that it was accessing while attempting to load the web page. This usually occurs when one of the two servers is down or not working properly.

Clearing cache and cookies is a great way to clean your browser allowing it to work more efficiently. Here's an article that shows you how to do that: Clear cache and cookies.
