Print Display not Working?

[ShynnSup]

I have print display turned on but I see no differences between the lines, even though I have used a print display of 40mm

Even more, the black line with default print width actually looks the wider one.

Alternatively you can duplicate the Continuous Linetype which has default Pixel width and change it to your preferred unit.
