Abstract
A method of printing an image comprises sending a data stream representing the image to a printer driver, generating a stream of print instructions at the printer driver, forwarding the stream of print instructions to a printer, and printing the image in accordance with the print instructions. The data stream or stream of print instructions is intercepted and processed so that the printer uses less ink to print the image than it would if the processing was not performed.
