Neither the black and white option or print gray scale will accomplish what I would like to do. Using the black & white option would drop out the gray fills and using the plotters grayscale wouldprint color lines as gray.
I would like to print a document that has color lines and gray fills (from the color pallete) on screen. The Proposed "print black, white & monochrome" command would print color lines as black lines and gray lines and fills as gray.
Why do I use color to differentiate line thickness? Zoom line thickness does not work well. At normal view (100%), one cannot distinguish between .03,.15or even .50. I also use color to differentiate classes. It is very difficult to draw in black onlyon complex projects. I was reluctant to start using color initially, but now I can't imagine going back to black only - its just to difficult to manage line weights and classes.
