There's a problem in Mathematica 3.0.0 for Windows that
causes colors (most typically in PostScript graphics,
but sometimes elsewhere) not to print out correctly to a
color printer when you have your screen resolution set to
256 colors.  If you set your screen's color resolution to
16 bit or 24 bit, then your color graphics will print out fine.
Note that this resolution must be set when you first start up
Mathematica...changing the resolution while Mathematica is
running won't make a difference.

I'm not so sure that the problems with printing out color
text are caused by this, though.  How is the text
colored...is the color inherited from a style, or did you
apply the color by hand?  It *should* work if you applied
the color by hand (e.g. Format->Text Color submenu), but
if the color is inherited by a style, then the style's
printing environment may be set to print that style is in
black and white instead of color (for example, the In/Out
labels of the Default.nb style sheet show blue on screen
but print as black).  This is done so that the styles
will print best on black-and-white printers.  Some of
the style sheets where colors are more prevalent have
two printing environments...a regular "Printout"
environment, and a "Color Printout" environment. If
you're using such a style sheet, then you can select
"Color Printout" from the Format->Printing Style
Environment submenu.

If you have a style sheet that doesn't have a color
printing environment, then you can edit the style
sheet so that the PrintOut environment prints in
colors instead of black and white.
