Today, I purchased a Canon Pixma MX350 printer, which is capable of automatic duplex printing. However, when I go to Print in Word, the 'Two-Sided Option' in the 'Layout' menu is greyed-out. Having spent a lot of time Googling and found several similar posts (but not for this exact printer), I understand that this is normal for a Canon printer, but that I should instead have a menu that says 'Duplex Printing & Margin', under which I can select duplex printing. However, I can't find any such menu and can't think of any other way to get duplex printing. The Canon driver I originally had (which comes from the CD provided) was 10.29.0.0. I found a newer one, 10.30.3.0, on the Canon website and installed it, but it didn't fix the problem. I'm running Mac OS X 10.5.8. Since my main reason for buying this printer was because I need auto duplex printing, this is really frustrating. Any help would be greatly appreciated!
