7. Use
EndPage(...)
to finish off. This flushes everything that was printed to
the printer and perform a form feed. This puts you at the top of the next
page and, if done right, Windows is reset, so the next
StartPage(...)
gets
things going again.
It is best to print something on the page regardless of whether the user said the
page was correct. This way the page is valid only if the valid message is on the
page. Remember that errors can occur while the system is trying to print the
void message and the void message may not actually end up on the paper. If the
absence of a void message means that it is valid, an invalid page may be
accepted as valid if the void message can not be printed.
