Hi Leo,
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.
The settings:
(setq ps-zebra-stripes nil
ps-use-face-background t
ps-default-bg t)
seem to do what you want.
The above settings could not work if frame parameters are changed
dynamically or if you use face remapping.
Regards,
Vinicius

`ps-print-buffer-with-faces' will print a dark background buffer
into a .ps file with white background. This makes the text
difficult to read.
This is a feature. See the variable ps-use-face-background for how
to override it.
I play with it. I put the buffer I want to print in another frame and
swap its foreground and background by modifying frame parameters so
that the change only happens in that frame.
But then printing still uses the global frame parameter's foreground
and background colors instead of the selected frame's. Is this a bug?
I don't know. Vinicius, could you please look into this? Thanks.
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)))
Regards,
Thank you for the answer.
However output from ps-print does not look good generally in a dark
background? Is this a known problem?
Ok, using the ps-default-bg default value (white) is not good when
using a dark background.
This is neither a problem nor a bug.
You could set ps-default-bg and ps-default-fg to a suitable color.
One possible way to improve ps-default-bg initialization could be set
it in ps-print with
(frame-parameter nil 'background-color)
The value of ps-default-fg and ps-default-bg variables are not changed
when frame parameters change.
Note that even the initialization above will not be good if the frame
parameters (background-color and foreground-color) are changed
dynamically.
ps-print also allows face remapping, so, the initialization above
could not be good depending on the colors used.
Regards,
Vinicius
