Please fix my Canon MP980 printer problem?

I'm running Mac OS X 'Snow Leopard' and lately whenever I want to cancel printing, I have no way to but to press the Stop button on the printer, which doesn't even work because it still ends up printing it anyway once the printer is resumed. Plus, on my computer I no longer have the printer icon pop up when I print, so there's no way to delete the print jobs. This sucks, please help me! Thanks.
