Is there any way of speeding up plotting. I really mean the time taken for AutoCAD to process the information before it gets to the plotter?
I have quite a few large 3D drawings which have upto 20 viewports with various iso views and sections.
I run AutoCAD with a Cadduct plugin. I have just installed a new printer - HPT790

The time taken to process the plot before it hite the printer is approx 5 minutes.
Time taken to actually plot (A0) is approximately 2mins - Which I am happy with.

Any suggestions?
