printing multiple files w explorer but asks to save changes.how not get the window?

Hi,

When selecting multiple excel files in explorer, you can right click and choose to print the selected documents.
All documents gets opened and printed but the files stay open and you have to manually click on YES or NO to save the changes.

Is there a way not to see this window appear. So documents get opened and printed and closes itself without asking anything.
Maybe it can be done with an option in the preferences. I'm not sure.

By the way the documents where created with excel vba just in case it's relevant.
Also the version of Excel is an older version, I think it was Excel XP or 2002/2003.

Thanks in advance.

Regards.
