The cartridges should still work but there may be a problem with the age of your computer or laptop. I know I had gotten a new laptop and the prior printer that I had would not work with it after I had done a driver update. So that could be an issue. I ended up having to buy another printer but gave the one I had away to a friend.
Sorry, there was a problem. Please try again later.No firewall connection to my issue.
