Hi. I have a Canon i475D printer and am having difficulty printing from it. I'm hooked up via USB and have fresh cartridges in it. I've managed to print a test page and a calibration page from the Mac itself (10.4.10), but that is it. I go to print a document from Pages, the printer clicks and whirls, does the usual thing a printer should do when it prints out... but all I ever get is a blank sheet of A4 paper. Any suggestions? This is the first time I've used this printer on a Mac. Has worked fine on XP previously. Cheers.
