With BookLightning, you can easily create booklets on your printer, just create a PDF document and drop it onto the BookLighting icon. Print the resulting booklet PDF, which BookLightning typically creates in less than a second, fold the pages and staple. Done.
All you need to do is set up your original document at exactly the size you want for the booklet, which will be 1/2 the size of the paper you are printing on as the pages get folded in half.
For the frequent booklet-maker, BookLightning even includes a convenient direct-print feature that lets you print booklets (via BookLightning) straight from the print panel of your application.
