How can I repeat headers in every page in printed reports. I saw an answer that IE support it, however for my need (Timeline) it does not work with IE nor Chrome.

From what I tested today and my prior look at this going back years, I THINK it can be done. But this type of thing requires time to explore every detail. I invest a lot of time on my own to keep up with web tech so I explore issues like this every day. But if you want a solution you are going to have to wait for QB or you can contact me off-world:
