Hi, ramisha08!
So that the Community can help you better, we will need to know exactly which operating system is running on your computer (i.e. Windows or Mac OS, and which version thereof) and your phone (Android or iOS, and which version thereof). Also, please let us know whether the printer is connected to your computer via a USB cable, or if it communicates with both devices via Wi-Fi. That, and any other details you'd like to give will help the Community better understand your issue!
If this is a time-sensitive matter, our US-based technical support team is standing by ready to help 24/7 via email at http://Canon.us/SupportCF or by phone at 1-800-OK-CANON (1-800-652-2666) weekdays between 10 AM and 10 PM ET (7 AM to 7 PM PT). We also encourage you to check out our Knowledge Base at that same link for answers to common questions.
Thanks and have a great day!
