I'll make sure you're able to print the Chart of Accounts without error, @enfuso.
A little troubleshooting may be necessary to get the print function working correctly. Does the button act any differently when accessed from a different web browser? I recommend clearing your internet cache to see if that helps, you'll find the steps for doing this in popular browsers from the link here. Also, try double-checking the pop-up blocker and see if it yields any notifications just as you click the Print button.
Thanks for reaching out, be sure to keep me posted on your results. I'll be watching for your reply.
