It is generally preferable to prepare a print job before launching it. PowerPoint offers modes and parameters to specify what you want to print (slides, pages, or comments) and how you want to print your work (color, gray scale, black and white, with frames, etc..).
The Slide Sorter view
The Slide Sorter view displays the slides as thumbnails. This mode facilitates sorting and organizationof the sequence of your slides for printing.
Print preview allows, before printing, to specify settings for what you want to print (documents, pages, comments, plans or slides).
