Claris and MicroSpot have confirmed that SuperLaser Spool 2.0.2 is compatible with both MacPlot and MacPlot Professional. However, you may experience difficulties when Pattern/Line quality is set to Final. The amount of memory required by MacPlot to do "hidden line removal" is considerable and may exceed the SuperLaser Spool's default buffer setting. If you need to use Final quality, make sure that the print buffer is set to at least 1024K within LaserQueue.
Please note that this is the only print spooler that will spool from MacPlot.
