Often I have to plot a drawing from another work group member.  I want it to be plotted in all black for the blue print machine since other colors do not show as well. 
I have been going to the layer manager and changing all layers to black AND going to the dimstyle dialog to change the dimension's line, extension and text colors to black.
I tried to change the colors using setvar's dimclrD but that doesn't work.
I want to have a lisp program that I can run to make these changes for plotting.  I know the style name and want to override dimensions colors temporarily.  I plot then I quit the drawing without saving.
Can anyone make a suggestion how to do this with less effort.

Which version of AutoCAD?Why not just set up a plot style, that will print everything in black, irrespective of the colour it is on the drawing?  Once set up it can be used again and again..  see here :  http://www.cadforum.cz/forum_en/forum_posts.asp?TID=1298&PID=3562#3562

I am using 2008.  I do have a plot style to print monochrome (all black) for colors up to 255 and I use it most of the time.  It won't work on RGB colors though but I can change them (all) in the layer manager to black.  I don't know why the dims still retain their color.  One other point is these drawings come from Inventor as a .idw file.  Shouldn't the plot style override the dim style?
