  • Patent number: 8830532
    Abstract: A printing control method of a printer is implemented in a printing system including an information providing device and a printer. The printer is connected to the information providing device for printing data sent by the information providing device. Once a printing driver program of the information providing device receives page data to be outputted, the printing driver program converts a number of first color components of the page data into a number of second color components and checks if any one of the second color components contains zeroes for all the content. If one second color component is found to have zeroes for all the content, this very second color component will not be sent to the printer, whereas the rest of the second color components will be sent to the printer for output.
