When I plot my diagram, some of the items do not plot. They show up just fine in the drawing on screen. They are white on screen but do not print or plot to paper, what am I doing wrong?

You have probably set the color of the item to color 255, which is explicate white. There is no white ink in printers so the white does not plot. What we suggest you do is set the color to 7 (which is black or white on the screen) depending upon what the screen background is set to) so it will print in black on paper. The alternative would be to set the print command to change the print color of 255 to be 7.
