7.4 Printing in black/white after colorizing
============================================
If you have a TeX or LaTeX document written with color macros and you
want to print it in black and white there are two options. On all
(good) PostScript devices, printing a color file will print in
corresponding gray levels. This is useful to get a rough idea of the
colors without using expensive color printing devices. The second
option is to replace the call to input 'colordvi.tex' with
'blackdvi.tex' (and similarly for the '.sty' files). So in the above
example, replacing the word 'colordvi' with 'blackdvi' suffices.
'blackdvi.tex' defines the color macros as no-ops, and so will produce
normal black/white printing. By this simple mechanism, the user can
switch to all black/white printing without having to ferret out the
color commands. Also, some device drivers, particularly non-PostScript
ones like screen previewers, will simply ignore the color commands and
so print in black/white. Hopefully, in the future screen previewers for
color displays will be compatible with some form of color support.
