Actually, thats not true. Simply put the following line at the top of your page that has headers and you can write errors out. I have been doing it for years.

Hello,
We try to avoid that function; phpdocx doesn't need to use output buffering to work but creating PDF files.
There's no reason to show an info message on screen; phpdocx is using php4log to get all messages.
Regards.
