Fun story I heard from an aerospace engineer - they were running some heavy simulations and producing graphs.
He found the printer that was emitting the graphs was actually more powerful than the (very expensive) machines running the simulations, to the point that converting the simulation to postscript (or some variant thereof) and running it directly on the printer was some orders of magnitude faster.
