Script for printing changed pages only

Question

Does anyone know of a script that will allow the printing of only those pages that have had changes made to them since a previous save? I'm a typesetter doing work only on books and journals and sometimes it's a bit tedious to keep track of the individual pages one works on. thanks,

Ok,
Here is a raw code. All you need to do is edit the script to specify the printer preset you want to use. I don't have a printer my self to debug but I think it should work.
Here is the idml to grab the object styles. Don't forget to apply on objects located onto the pasteboard. The script look for these objects and grab the page name next to them to finally print these pages.
Hope it helps,
