Take a look at Printed Documentation and Print Issues on my
site.
Don't forget that what appears in the right hand side of
print layout as the TOC is not synchronised with the TOC itself,
except when you first create the layout. Either you manually edit
the print layout to synchronise it or you use the left arrow to
clear it and the right arrow to reinsert it.
Titles and subtitles are in fact book and topic names so if
they are the same, they appear to be the same thing printed twice.
