I have both a Canon printer and a hp printer. My Canon printer was connected with my computer earlier. So when I tried to connect my hp printer, I faced an error that occurred at that time. I learned about [removed per Forum Guidelines] after searching many websites and got the solution. But after that suddenly my Canon printer stopped working. What should I do now?
So that the Community can help you better, we will need to know exactly what model printer you're using (it's usually on the top or front of the unit), any error messages you're seeing, and the Computer Operating System you're using (Windows Vista/7/8/10 or macOS 10.x), as well as the way you connect to your device (USB or networked via WiFi or Ethernet).
Any other details you'd like to give will only help the Community better understand your issue!
