Re: ps-print-buffer-with-faces doesn't use selected frame's background

[Richard Stallman]

    Well, the ps-print commands have a comment:

    ;;;###autoload

    just before the command definition.


Yes.  So when you run one of these commands, it will load ps-print.
However, if you type C-h v ps-default-bg before that, it will not see
that the variable even exists.

    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?

    Ok, could I implement it now in Emacs 22 before the release?

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