Genuine OEM Canon PIXMA MX300 Ink and Supplies
PG-40 black ink is listed for the Canon PIXMA MX300 as an individual cartridge and a twin pack. The twin pack groups black cartridges together, making it a different choice from a black-and-color bundle.
Toner Buzz carries genuine Canon black and tri-color ink listed for the MX300. The PG-40/CL-41 ink-and-paper kit combines black and color supplies with paper, while individual cartridges keep those ink purchases separate.
