+ 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.
