Select "Export Book to PDF" from the fly-out menu in the books panel, then select in the Export Adobe PDF drop-down menu, which type of PDF you want, for example, PDF/X-4. indicate spreads or single pages, use document bleed setting and any printers marks you want.
I have printers that have specifically asked for PDFs with no marks.
All of the information for bleed and trim is built into the exported PDF and they prefer to add the marks themselves.
Perhaps speak to the printers about this possibility.
