Let me guess: Your printer asked you to do this, right? Your printer is living in the 1990s and is probably trying to place this in a QuarkXPress file. And I'll suggest you should run, not walk, to find another more modern printer!
But, if you have to do it, you could export as a PDF file (including the marks, bleeds and slug). Then in Acrobat, choose File > Export (Acrobat 9 Pro) or File > Save as > Other Formats > Encapsulated PostScript (Acrobat X Pro).
