printing in color

I am using D S 16, x64 in win 7.  I have a dwg with white, green, red, and yellow areas.  The yellow areas are text.  The white are lines.  The green and red areas are hatched solid areas.  When I try to print the dwg I only get the text and white (which of course prints as black) and the green and red areas do not print at all.  I know the printer is O.K. as it prints all colors in other programs and there is enough ink.  I assume the problem is a setting of some kind, but I can not find it.  I have looked in the Tools/Options/Printing but have not found anything.  Can anyone help?   Jim
