Digital BW, The Print

I use EPSM on my 4800, and a friend asked me if she could use it on
her 2400. I told her to by the 17 x 22 sheets, cut them to size, and
use the scrap for test prints. But I believe the 2400 ABW print dialog
does not allow EPSM to be selected as the media choice. What is the
work around here for those of you printing on this paper with the 2400?
