It's possible now to print single resource with or without answer. After carefull testing on all kinds of problems I'll add this option for any other items from printing menu. (Some additional technical work still has to be done - Subroutines,...). Note, that I've tested this feature only on the numerical responce problems.

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.
