I produced a simple booklet with Publisher today. General steps (I use the german version; maybe it is slightly differnet in English):
Note, that you need a booklet with 4 or multiple of 4 pages.
Print: with "File" > "Print". In the setup window use:
Printer: PDF printer (a PDF printer e.g. Adobe, Kofax etc.)
Button Properties: use Landscape format (mostly)
"Layout" > "Model": "brochure"
"Bleeds and marks": activate "incl. Bleed areas", "incl. Printer brands", "Cutting marks", "passer Marks"
Store the file
Print by using a duplex printer OR first by printing all odd number pages (1,3,5,...), turning around the pages (by taking note of the orientation and page sequece), followed by printing the even numbers (2,4,6, ...). For both, your printer needs to positionate exactly, because of the cutting marks.
As @Old Bruce said: use a cutter, a cutter pad, lineal and your hands
Sometimes, it's beneficial when using your hands and seeing the results.
