often very different from paper white, so this may result in color

Windows ICM Color Matching
Windows 98, Me, 2000 and XP only. This affects RGB data only.
ICM is the color management system built into Windows.
Windows ICM uses ICC profiles for your monitor and printer; these
profiles describe the colors that your device is capable of

Color Management tab of the printer driver.

Windows ICM uses the information in these profiles to convert colors
in your documents to colors that the printer can reproduce. The way
