Javax.print monochrome doesn't work

Question

I'm developing an application that uses javax.print and icepdf.

When I try to print a colored PDF in black and white, my printer always prints it in color...

I have used theses properties:

printRequestAttributeSet.add(Chromaticity.MONOCHROME);
hasDocAttributeSet.add(Chromaticity.MONOCHROME);

But my printer still print this in color.

How to print a colored pdf in black and white?
