Printing color separations as composite to PS laser printer

[drcpub]

I am trying to print a separation in color ink, the same color as the pantone color,  in this example PMS 254 C. All setting seem to suggest it should work, please see screen shots, the cmyk channels are X'ed out.  Instead of the laser printer sending 1 separation in color, it still sends the pdf to the printer as a complete composite, all colors.  Is there any way to print the separation in color?  I do not want to print it as black in by way of sending separations or in-rip separations.  I need color overlays.
