Solid fill wall will not print in black and white.

[Lilidesignbuild]

Some of my walls in floor plan have gray solid fill. When I send to layout they look perfectly fine. However, when I setup the page to print in black and white, the solid fill goes away and I can see only lines, no fill. 

 

Am I doing something wrong here? or is something that Chief needs to fix?

You might want to post a test plan file but some colors do not have enough density to print and they will show fine in plan or even PDF.

 

There is a setting in Preferences > Display   Color Off is "Black and White" or "Gray Scale"  that should fix your issue if set to Gray Scale.

I ran in to this several years ago. I always print to black and white and some of the colors used for solid fill will not show up; orange is one I found first. It was trial and error for me until I found those that worked for my taste. I found that using a color such as red or red-brown, with the transparency set to various settings (70-90% for me) worked well.
