To solve Canon Printer Not Printing, make sure the wireless Canon Printer is set up with the available Wi-Fi connection properly. After that, select Printer from the menu to clear the print queue and enable smooth printing. Additionally, remove the paper stuck in the printer head and clean it so you can take the printed documents with you at any time. If the ink cartridge is running low, your printer won't be able to print anything, so you could also need to replace it.
