If you are here you found there is no easy way to print just the notes, without any slides, full or thumbnail.
Here is a solution for those with linux available, or perl on windows, possibly cygwin.
This script reads the odp file and outputs simple text:
It also needs: XML::LibXML::PrettyPrint and Data::Dumper
when debugging is turned on.
Since it actually unwinds the ODP format, there is a chance it might now work with version changes,
so please advise me.
