The Print in pure black and white option is not supported when printing on glossy paper. ● In the Mac OS X Print dialog: Go to the Color Options panel and select Grayscale from the Mode drop-down list.

dependable color results.

Color management options
The aim of color management is to reproduce colors as accurately as possible on all devices: so that, when you
print an image, you see very similar colors as when you view the same image on your monitor—assuming that
your monitor is calibrated and displays colors correctly. Color management is highly dependent on the paper
type loaded at the printer, so take care to select the correct preset for the paper type you are using.
The color management options for your printer can be selected from the
Color
menu in the Windows driver
dialog or from the
Color Options
panel in the Mac OS X Print dialog. In some applications you can make the choice
in the application itself. Consult the HP Support Center for guidance on how to use the color management
options of your particular application.

: In this case your application program must convert the colors of your image to
the color space of your printer and paper type, using the ICC profile embedded in the image and the ICC
profile of your printer and paper type.
Printer-Managed Colors
: In this case your application program sends your image to the printer without any
color conversion, and the printer converts the colors to its own color space. The color management in the
printer is done using a set of stored color tables. ICC profiles are not used. This method can produce very
good results with supported HP paper types. There are two color spaces that the printer can convert to its
own color space using the stored color tables: sRGB and Adobe RGB.
sRGB
emulates the characteristics of the average computer monitor. This standard space is endorsed
by many hardware and software manufacturers, and has become the default color space for many
scanners, cameras, printers, and software applications.
Adobe RGB
provides a larger color gamut than sRGB. Use this space if you need to do print production
work with a wide range of colors.
Printing in grayscale or black-and-white
