Network printer stops working after restart

Today, I found my Canon printer not working after being powered on. It was working well before the last power-off. During the restart, there was a message saying that the IP address of the printer was changed.

I guessed the IP address change could be the problem so I decided to change it back. To find the old IP address of the printer, I opened the Control Panel and entered Devices and Printers. Then I right clicked on the Canon printer, and chose Printer properties. There I clicked on the Change Properties button, and then clicked on the Ports tab. I found the Canon printer in the list and clicked on the Configure Port button. The IP address of the printer was shown there.

Then I went to the Network Settings menu of the printer and disabled the DHCP protocol and set it to manually configure the IP address of the printer.

I also needed to login to the router to reserve the IP address for the printer so that the router wouldn't assign it to other devices when the printer was off.

After all the changes, the printer worked again.

In summary, to make a network printer working properly with Windows, we need to give it a fixed IP address. If the printer has already been set up in the Windows, we can make it always visible to the Windows by:
  1. Find the IP address of the printer in Windows.
  2. Disable DHCP protocol of the printer and give the printer a fixed IP address as the above one.
  3. Login to the router and reserve the IP address for the printer's MAC address.
