  I have a couple of postscript saving examples
  that include the following geometry parameters
  which produce  .ps  files that render the same
  as the canvas drawings when viewed in ghostsript.
   
retval = canvas.postscript( 
           file       = "image/ps/xyzzy.ps , 
           height     = 400 , 
           width      = 400 ,
           pagewidth  = 400 , 
           pageheight = 400 ,  
           colormode = "color" )

  Perhaps adding the geomerty parameters
  might help.
