Even if you get rid of all the problems with the pen and the ink
and the line width and the layer thickness the plotting is still very,
very slow.
(i mean really slow).

I also could not manage to plot a pcb with the holes in the pads
open (for centering the drill) which quite annoyed me...

I tried it for a while, and was not satisfied, not at all.
TT delivers better results much faster and easier for me.

The plotter is still a good choice for component legend.
(But i did not yet bring my libs up to it and i also don't require
it for my own boards...
- after all it adds not much functionality to the circuit itself ;-) )
