Well, now I see what causes that, it's my ~/.emacs file.

If the ~/.emacs file have:

   (setq initial-frame-alist (append '((background-color "DarkSlateGray"))
                                     initial-frame-alist))
   (setq default-frame-alist (append '((background-color "DarkSlateGray"))
                                     default-frame-alist))
   (require 'printing) ; or (require 'ps-print)

then ps-print is loaded before initial-frame-alist has any effect, so, 
ps-default-bg is set to white.

I think that initial-frame-alist will take effect only after ~/.emacs is 
loaded.

Ok
