Composite Black

The printer driver produces composite black by mixing the colors of the color print cartridge to produce "black" ink. The printer driver uses composite black instead of true black ink because:

l The HP DeskJet 2xx/4xx printer holds one color print cartridge or one black print cartridge. Therefore, any black on a color page must be printed using composite black.

l In most DOS applications, all of the black in any color graphic is printed with composite black. The printer driver does not separate the black from the color in a color graphic. Contact the DOS application vendor for color driver information.

Composite black is slower to print, depletes the color print cartridge more quickly. Additionally, the output may appear slightly greenish.
