If you really need to have full control on your "virtual printer" output, have a look at gs arguments : http://www.ghostscript.com/doc/7.07/Use.htm

Then, as you say, 300 dpi : * is most often enough for common color map printing * should be increased to 600 dpi for b&w images e.g. text+thin black contour lines on a white bg to be sent on a laser printer, andbut should be considered the least acceptable resolution for high quality paper production. I agree that it's useless beyond 600 dpi.
