windows photo gallery only prints in b&w

I am using an HP CM1017 MFP which works fine with all other programs.
But for some reason using Windows Photo Gallery, I cannot print in
color. Preview window shows color, grayscale is unchecked, etc but it
prints in black and white every time. I even tried using the sample
pictures that came with program. Still come out in black and white. It
worked fine when I wanted to print in b&w, then I unchecked grayscale
and now it won't stop printing in black and white. I even tried
shutting down all programs and restarting computer. Please help...
