I have an Intel Duo Core 2 iMac and a Canon iP4300 printer, hooked up through USB. All was working well until a few days ago, when suddenly, whenever I try and print, I get an error message. All it says is "Error while printing.". I tried reinstalling the printer but it doesn't work. When I boot into Boot Camp and print from XP, everything is fine, so it's not the printer. Any ideas? I'm running 10.4.8.
