Comment(by annakrat):

 There are a few problems:

 * Ghostscript is missing (not in OSGeo4W framework)

 * if it is installed it is not on the PATH

 * from the PIL source code (C:\OSGeo4W\apps\Python27\Lib\site-
 packages\PIL\EpsImagePlugin.py):

 {{{
 def Ghostscript(tile, size, fp):
     """Render an image using Ghostscript (Unix only)"""

 ...

     command = ["gs",
                "-q",                    # quite mode
                "-g%dx%d" % size,        # set output geometry (pixels)
                "-dNOPAUSE -dSAFER",     # don't pause between pages, safe
 mode
                "-sDEVICE=ppmraw",       # ppm driver
                "-sOutputFile=%s" % file,# output file
                "- >/dev/null 2>/dev/null"]
 }}}
