Tim,
It plots whatever's shown in drafting, (and picks up on line weight by colour). It also can produce a good quality (300dpi) tiff straight to disk of an entire drawing.
The only drawback is that you need a plug-in viewer installed to be able to view/plot a file containing a raster image correctly. I think BCT supply the viewer free of charge, but if you are interested it would be worth dropping them a line.
