It's the "may" and "recommended" and such that are worrisome.  The
team here at Chrome would like some reasonable assurance that the
content will print the way it appeared on screen, and clipping is
their ideal behavior.  On browsers where we have less than sufficient
control, we just won't print within the browser at all - we'll do a
trip back to the server and create a PDF there.

Well, yeah.  That's fine.  ^_^

I didn't see anything either, but the team thought there was something
there, so I was going to ask to make sure I wasn't missing something
before I reported back to them.
