Why does Pages ask me to save changes when I only open a file and print it?

Question

I have documents that I open regularly but only want to print (and not make changes to).  But, even if I open them and do nothing other than print them, Pages prompts me to save changes when I close the file.  Why is this? 
If I've had the document open for a while, I'm always concerned that maybe I've made changes that I want to save and forgotten.

But it always, always, always ignores it, fruhulda. That's what I'm saying. A brand new document on a brand new computer with a fresh install of iwork, and the same thing happens. Every time I open it and print--Do you want to Save? Do you want to Save?
For instance, I have a contract form I use regularly and I get that every.single.time even though I always use the same printer, and have hardly ever used the printer that pages has chosen as my default printer (a medium format inkjet with archival ink that costs far too much to use for things like correspondence). It is not my default printer in OS X, incidentally. No matter how many times I tell Pages to save the information about the printer, it will not. And I also get the same nag on the rare occasions when I do use the printer that pages has chosen (usually by mistake because I forgot to change it in the print dialog).
Perhaps this is a localization-specific bug and that's why you don't see it.
EDIT And most oddly, it happens just the same in lion with the current version of pages, which I would have thought should have autosaved that change without asking me about it.
