Annotator plots to Xerox 8830

I'm having some difficulty plotting from annotator (SD 7.11). I can't get it to plot line widths or select paper sizes correctly to a Xerox 8830 plotter. It's supposed to be DJET750/R compatible according to Xerox but I'm not convinced. It plots to correct scale and uses the one line width just fine. I've written a little perl filter that forces it to select the right paper size so that's not really a problem. Getting the line widths right still is though... ME/10 plots to it just fine (with line widths and everything). Any suggestions? Thanks, -Chris W.
