I have already read all the post and tried all the suggestions on this subject and it still does not work.  It is a bug that has not been fixed.  I have an HP DesignJet 510 and a Xerox Phaser 6280.  Yes, I'm printing from the sheet view and selected "additional options" and tried all the print style tables monochrome.stb, allblack .stb etc.  Draftsight will not print a drawing with layers and colors all black.  I'm using version 11.2.802.
