This is my first try with map automation so I'm starting small.  I just want to print out all the mxds in a directory.  I started testing with just one MXD and I'm already having problems.  Can you configure printer / page settings with arcpy?  
My test MXD is a color 9.3 MXD, with 11x17 format.  It keeps coming out on 4 8.5x11 sheets of paper in B/W.  I've saved the MXD after setting the color and page size but when I go back in those settings are lost.  Any ideas?
import arcpy.mapping as map
mxd = map.MapDocument(r"H:\Data Release\sect_s28t23r41e\maps\phshalebuffsect.mxd")
printerName = "\\\\DFWPSOLY01\\DFWHN5W5185b" 
map.PrintMap(mxd, printerName, "PAGE_LAYOUT")
del mxd
