See lonhelper.pm documentation for discussion of the helper framework.
Apache::lonprintout::page_format_state is an element that gives the
user an opportunity to select the page layout they wish to print
with: Number of columns, portrait/landscape, and paper size. If you
want to change the paper size choices, change the @paperSize array
contents in this package.
page_format_state is always directly invoked in lonprintout.pm, so there
is no tag interface. You actually pass parameters to the constructor.

=head1 Helper element: page_size_state
See lonhelper.pm documentation for discussion of the helper framework.
Apache::lonprintout::page_size_state is an element that gives the
user the opportunity to further refine the page settings if they
select a single-column page.
page_size_state is always directly invoked in lonprintout.pm, so there
is no tag interface. You actually pass parameters to the constructor.
