How do Epson drivers handle color profiles when printing in ABW mode?

Do they ignore any embedded profile?
Make a conversion based on the embedded profile?
Assume that everything that comes to it is sRGB or AdobeRGB?
Check to see whether you are using genuine Epson inks and punish you if you aren't?

It might be helpful if we --- the group --- could agree on simple workflows for things like using ABW and put them in our "Files" section.   I'm sure the information I need is somewhere in our archives, but it is not readily retrievable.

The simplest workflow question:  When using ABW with the Mac Epson diver, should I tell PhotoShop (or reasonable facsimile) to control color, choose my color profile for the paper I am using,  and then tell the Epson driver to use ABW?  Or is PS's attempt to control color going to make any difference (or make things worse)?

Thanks.
