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.
