Welcome to the Canon forum! So that the Community can help you better, we will need to know what model PIXMA printer you are using. Any other details you'd like to give will only help the Community better understand your issue.

The printer will have to be reinstalled on your computer in order to be able to print on the new network.
If you have any difficulties with this process, troubleshooting with our support group will be needed to narrow down the cause of your issue. Please contact our support group using the "Contact Us" link below for additional assistance.
