+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.

+
+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.
