ps-print does not get color frame parameters; it only deals with faces.

The variables ps-default-fg, ps-default-bg and ps-use-face-background 
are only relative to faces.

So, to get the frame parameters to print you could use some function like:

(defun my-ps-print-buffer-with-faces (&optional filename)
 (interactive (list (ps-print-preprint current-prefix-arg)))
 (let ((ps-default-bg (frame-parameter nil 'background-color))
       (ps-default-fg (frame-parameter nil 'foreground-color))
       (ps-use-face-background t))
   (ps-print-buffer-with-faces filename)))
