Digital BW, The Print

I created a profile using QTR. It produced a profile that is available
in the standard print driver but it seems that the CS 3 plugin from
Canon does not recognize grayscale profiles.
Is there a way to produce an RGB/Grayscale profile from QTR or has
someone out there got a work around.
The reason for not using the standard printer driver is that I get
much better prints using the plugin.
Any and all help would be appreciated.
