This directive is legacy from the original
chord program. This program had the ability to print multiple song pages on a physical paper, so called N-up printing.
With N-up printing, a
new_page directive generates a new song page. The
new_physical_page directive would force printing on a new sheet of paper.
N-up printing is no longer supported by ChordPro. PDF viewing and printing tools can handle this should you need it.
