Hello and thank you for your question.
You have already replaced the ink cartridges, and I assume the printer has paper, and that you have checked all of the connections. Check and make sure your printer properties/settings are okay. If so, then I suggest for you to reinstall your printer. Go to Start, Settings, Printers folder, delete existing printer and then reinstall your printer. I think this will take care of your printing problem. If for some reason it doesn't, you can go to Cannon's website and download a "New" current driver for your printer. If after all of this and it still does not work then you may have a hardware problem, mechanical, with the printer itself, and would need to be ckecked by a qualified technician.
Good luck!
