Is there a way of configuring Excel so that every time I open a document it includes a footer? I want to have every document to have a path to the file printed when printing. I'd rather not use a template.

Not unless you use a template, which you say you don't want to do, or a macro (eg in your personal.xls(m) file) that intercepts an event such as file creation, saving, closing or printing.
