About schematic Plot

Hi, I meet a new problem recently when I want to plot schematic to pdf. 

My .cdspolotinit file is shown below, I choose PDF_1000dpi as my plotter

Encapsulated PostScript|Encapsulated PostScript: \
 :manufacturer=Adobe: \
 :type=epsf: \
 :resolution#300: \
 :maximumPages#1: \
 :paperSize="5x5 inches" 1500 1500: \
 :paperSize="8x8 inches" 2400 2400: \
 :paperSize="Unlimited" 72000 72000:

PDF_1000dpi|Small Postscript: \
        :type=postscript2: \
        :spool=ps2pdf13 - > ~andy_zhu/cadence/plot/plot_{cellName}.pdf ; (acroread ~andy_zhu/cadence/plot/plot_{cellName}.pdf &): \
        :resolution#1000: \
        :maximumPages#30: \
        :paperSize="A" 8000 10500 250 250:

After I use design-->plot-->submit to plot schematic I can get a pdf,but its size is 0kB. Why? 

Best Regards,
