Does your drawing use any layers with the colors 10, 210, or 255?
Your 10 and 210 say to use the object color, and 255 says it is 252,252,252.
If you are expecting to see lineweights as shown in your Layer Manager, or
by Object, you have over-ridden that in the ctb file because all the colors
also have their lineweights specified in the ctb dialog box. All of those
should be set to "by object". That will allow you to set the lineweights in
the layer manager by Layer Name instead of by Layer Color. Or if you
want...to set lineweights by each drawing object in the drawing.
Another thing to look at is if you are using polylines of a certain width.
Those widths have to be zero or at least wider than the lineweights called
for in the ctb file or in the layer manager, or by object. If the polyline
width is thinner than the pen lineweight to be plotted, AutoCAD will default
to a zero lineweight when plotting.....you can see this also if you turn on
the LWT button.
The plotter can't plot a 0.4 pen in a 0.2 wide polyline, so it has to use a
zero width line because plotters can't think. Only you get to think.
So a quick and dirty solution to the lineweights not plotting is to set all
the polylines to a zero global width. You can test this and use undo if it
doesn't change things for you.

It will not print in black and white nor will the thicknesses plot
