How much I reduce the ink comsuption printing in draft versus Normal or Best on the ink jet and laser printers? -

Hi Edwin Between normal and Draft, you save 60% of the ink. What happens in draft mode is that, the printer uses less ink because due to the output being at half the resolution than in normal mode. As for Best vs Draft, you save 75% of the ink.

That depends upon the printer, it is generally anywhere from 20-50% on draft versus normal. Best again depending upon the printer can use up to 6X the ink used to print on normal.
