If the field is in the header or footer, it will update when you print (and
possibly when you Print Preview) even if you don't have "Update fields"
checked on the Print tab of Tools | Options (fields in the header and footer
are always updated); otherwise, you do have to update manually (you can also
use Ctrl+A, Ctrl+F9 to update fields in the document body).
