How to make "Do you want to save" popup go away - batch print date stamp related

Adobe Acrobat has changed the way it handles files from the last two versions we used (9.5 and X) to DC.  One of the changes is that, apparently, it wants to save "changes" to files marked with a date stamp.  We process thousands of documents a day in peak season and need to date stamp them in the corner.  In the past, we'd use the action wizard or its predecessor to do this and had no issues with this.  But now we have one.  The command we used "Add header and footer" specified a date stamp in the upper right corner.  The next command was the print command with no files specified.  When run, this prompted us for the files to print, added the date then went onto the next one.  Now, it prompts to save the change to each file.  We don't want that. 

What is needed is an option to suppress this question, in effect, automatically discarding any supposed changes to the docs.  We aren't really changing the docs, we're simply printing overtop the docs.  I imagine if someone did want to add the date to the file there should be a way to automatically save all the files without prompting or prompting only once per run perhaps.

So, if that can be accomplished, let me know how, please.  Alternately, if there's another way to print the date in a very specific location on a doc in a specific font as we did with the add header and footer command and in such a way that Acrobat doesn't think this is a change to the doc then prompt us each time, so we could do the same batch printing of multiple files, I'd settle for that.

Again, please let us know if this can be corrected.

Thanks.
