One of the most common reasons behind the “​​Canon Printer Not Printing Black Color From Computer” issue in the Canon printer is an empty cartridge. You should first check whether your cartridge still has ink. First, open the printer’s front door and remove the cartridge slowly and carefully. Look out for its ink levels. If there is little or no ink left, you should replace the cartridge with a new one. After you have put the cartridge into the right position, take a print test to check whether the problem has been solved.
