Welcome to Justanswer.com, my name is Dustin.I'm sorry to hear about the issue you are having, I will do my best to help you resolve it.
What is the full model number of your Canon printer, such as an Mx922 or Mg5320 ?
Also, the cartridges you put in, were they also a year old? Or were they brand new canon cartridges that you just purchased?
Your best bet, is to remove the printhead and clean the contacts on it.. Almost certainly what happened is that the ink inside the printhead dried up after sitting for a year. So you need to try and flush it out..
This video shows the process on a very similar model. https://www.youtube.com/watch?v=pEkKGBUSwNg
Do the best you can to clean that printhead, as the cost to replace the printhead is steep.
If you get stuck or have any questions, let me know.
