Printing of (Index Card) Titles

Every Index Card has a title.
This title is shown, too, when I switch to the editor.
The titles are shown in the tree view of the project, too.

But somehow the titles are not printed, when I print the document.
I remember that there should be a switch somewhere to turn printing of titles on/off.
But I am not sure, if I am correct.

Can You please help.
Thx a lot!
