It is of course unacceptable, at this late date, that VW can not print a grayed layer. Why have a grayed layer at all if it cannot be printed? Is it possible to change the color of the VW default gray so that it can be printed. I have a work around using Gimp where I increase the saturation, density etc, of the printer in order to make the gray layer visible but if I could darken the gray by two shades to begin with it would be a lot easier.
