How do I print my outline in color in Outliner 4?

I’ve just upgraded from version 3 to version 4 of Omni Outliner Pro. My previous outlines had columns that were color coded. The color shows up on the screen now, but not when I try to print. I’ve gone into Page Setup and the Print Dialogue boxes. I’ve changed “Auto” to “On”. Still nothing.

I’m guessing I’m missing some setting somewhere by I couldn’t find the answer in the manual or the Help search. So I turn to you all!

I haven’t tried to redo all the color yet, since I wanted to be sure prior to completely reformatting all of my outlines.

Thanks,

Paul
