I just bought a new Imac last week with latest software updates, and tried to print up a Christmas newsletter I prepared on Pages, but it only comes out in black and white. My printer is a HP 970 cxi. Does anyone know if this is compatible? Ive been to HP site and updated drivers, called my local Apple re-seller and no-one can help me. Is there anyone here who can help? I desperately need to print in colour quickly! Thank you.
