Hi AC, for getting it ok on the monitor you can do the following: Open
the file

C:\Program Files\Wolfram
Research\Mathematica\3.0\AddOns\StandardPackages\Graphics\Legend.m,

find the line in the definition of Plot (the second one) which reads

ps = ps/.{Dashing[x_] -> Dashing[2/0.3 x]}; (* scale dashes *)

and change it to something like

ps = ps/.{Dashing[x_] -> Dashing[2/0.3 x],
		Thickness[x_]->Thickness[10 x]}; (* scale dashes *)
