How can Canon printers print with color ink cartridges without black ink cartridges?

Most Canon printers don't support monochrome. If the original black ink cartridge is still there (if there is no ink, it should be put in the printer), find the printer driver properties, and then click Maintenance. One kind of ink cartridge is set to print only with color ink cartridges, so that black ink cartridges will not be used, and all printing will use color ink cartridges.
