To print a single slide, notes pages or 6 to a page (or similar) you have to click on 'print' and then click on the option you want(the question will specify how they want it printed)
Also you can choose which slide you want to be printed by typing in the slide number i the space below print all slides.
When printing, you can also add your name in the Printed Page header/footer (not on each slide) by clicking on 'edit header and footer' then selecting the box you need!
