With the Canon PIXMA MP640R, you can start saying goodbye to wired printing and say hello to convenient and flexible wireless printing. Now, you can be free of the wires that bind you and enjoy the convenience of printing and scanning wirelessly from any Wi-Fi enabled computer or device while you're in another room. But just like any other Canon printer, your PIXMA MP640R can also run out of ink when you least expect it. So, make sure to always have replacement Canon ink cartridges on hand.

Our compatible Canon ink cartridges work and fit just like the OEMs but cost up to 70% off their price. So, buy here now!
