Humm, trying the initialization above, I can see that ps-print is loaded before .emacs file is loaded. So, the background is white when ps-print is loaded and, only during .emacs loading, the background is changed.

I suspected as much.  What causes that?
What does the backtrace say?

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"))
   (setq default-frame-alist (append '((background-color "DarkSlateGray"))
   (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, could I implement it now in Emacs 22 before the release?

Yes.  But please also investigate what causes ps-print to be loaded
