Copyright cut off printed page
NoteWorthy Composer adds the print margins to the edge of the paper. It does not add the print margins to your printer's unprintable area.
It is an option of the printer whether to send information to the application noting the printer's unprintable area and the print start point. NoteWorthy Composer may not be receiving this info from your printer and that is why Print Preview may show the copyright info on the page and then it does not print.
You will need to increase the bottom margin.
