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

[Richard Stallman]

    I made some tests and it is not possible to use frame-parameter in the 
    ps-default-fg and ps-default-bg initialization, because, during Emacs 
    initilization, ps-print is loaded before the frame parameters are set.

1. Why is ps-print loaded before the frame parameters are set?
In what case is that so?

2. It would be possible to avoid computing the defaults for
ps-default-fg and ps-default-bg until a command is given to print
something.  Would that solve the problem?
