This message is no longer necessary. If people have further trouble with
this issue the solution is not to add 'helpful' text messages that
nobody will read, the solution is to take the multiple "things to do"
out of the helper and institute a "one screen, one thing to do" policy
for helpers.
First rule of the web: People don't read. (But they will happily take
the opportunity to blame you for not having help if you don't provide
it, even though they won't use it.)

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.
