I purchasedthe MF644Cdw and had no success printing from my Mac with the software installed. My iPhone and my wife's new Mac easily printed to the Canon with no software, so as a quick fix I deleted the software from my Mac and the printer worked for a month. During the month, my wife's new Mac stopped printing to it, then my Mac stopped printing to it, and my iPhone quit printing to it, although it (says the printer is off line).
Any ideas?
