You can use the following script, available in the JavaScript™ for Acrobat® API Reference:
function DumpBookmark(bkm, nLevel)
{
var s = "";
for (var i = 0; i < nLevel; i++) s += " ";
console.println(s + "+-" + bkm.name);
if (bkm.children != null)
for (var i = 0; i < bkm.children.length; i++)
DumpBookmark(bkm.children[i], nLevel + 1);
}
console.clear(); console.show();
console.println("Dumping all bookmarks in the document.");
DumpBookmark(this.bookmarkRoot, 0);
Copy above script, open the interactive console with Ctrl-J (Win) or Cmd-J (Mac), select all the lines in this code and Ctrl-Enter. You will get a list with all the bookmarks that you can copy and paste in a text editor to print it.
