It acts more like a print screen of the panel rather than printing the Factbook results in the panel.
Replication
- Open Factbook
- Enter "Barnabas" as the topic
- Expand all sections (so all results are visibly available by scrolling)
- scroll down a page or two
- Execute "Print/export" from panel menu
The print preview only shows the results visible in the panel at that position, It does not show all the results for the whole topic.
The same thing happens for a Bible reference.
If the panel is the bottom half of a column, it does the same thing - only the print preview is smaller because the panel is smaller.
