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

[Richard Stallman]

    Well, I don't know why, but when the initialization code for 
    ps-default-bg and ps-default-fg include frame-parameter,

What is the precise test case that you tried?

    If the variables have a value (let's say, 'frame-parameter), the value 
    of them is calculated when any ps-print command is activated. And it's 
    used frame-parameter function to get the color value.

I don't understand what that means.  Could you show me the code you
have in mind?
