If your Canon printer does not respond, verify the connection of all cables, and reset the printer and computer. Go to the Control Panel of your computer, click Printers, and select the Canon printer as the default printer. Cancel all printing jobs in the queue, and attempt to print again.
A printer may not respond due to various factors, such as connection settings and the condition of the printer. If one USB port fails to respond, connect the printer to a different USB port of the computer.
If you have a wireless Canon printer, connection problems can occur when the printer fails to detect the right network name before printing. To select the right network name, press the Setup button on the printer, go to Wireless LAN Setup, and then press OK. Choose Easy Setup, press OK, and then select Access Point. Provide the Wi-Fi password, press OK, and then insert the setup disk into the computer.
On the AutoPlay window, run the setup program. Provide the required details, such as the place of residence, country or region, click Easy Install, and then click Install. On the new page, click Use the Printer On Network, and then click Next to begin installation. Click the Complete button when the Setup Completion window appears, and then try to print again.
