This one’s pretty straightforward. If your printer has an empty black ink cartridge, then your “Canon Printer Not Printing Black” and white documents issue appears. Unfortunately for printer owners that have 4 or more ink cartridges inside, it gets a lot worse. A printer that uses 4 different cartridges, such as black, cyan, magenta, and yellow, will need to have enough ink on all cartridges to print black and white documents.
