Thanks you very much, Mark - for some reason I was not seeing those options. I just deleted the printer and did a re-install and now I have the options.
Now I see the the new media in the driver, EXCEPT when printing from iProfiler - I do not see the BC Custom media that I added. There is no Custom category available at all when the driver is started from iProfiler, but it is there for other applications.
Maybe this is part of the process iProfiler turning off color management, but it seems this will cause a problem with my printed target, no?
