4. start new Emacs session
5. type: C-h v ps-default-bg RET
==>> "#ffffff" (white)
That is quite strange, because when I do emacs -Q and
C-h v ps-default-bg RET it says that variable isn't defined.
I wonder, have you done something to cause ps-print to be preloaded?
2. set in emacs/lisp/ps-print.el file:
(defcustom ps-default-bg (frame-parameter nil 'background-color))
Please try this:
(defcustom ps-default-bg (progn (debug) (frame-parameter nil
'background-color)))
Then you will go into the debugger when that initialization gets run,
and you can see when it gets done, and what code runs it.

With your explanation, I now understand that idea, and I think it is a
good one.
