Thanks for joining and posting in the Canon Forums!
Based on the information you provided us with, you probably own the PIXMA MG6821. The printer model name can often be found on the front of the unit near the top or bottom corners. The serial number for the unit is a little trickier to find, as it can be located on the back or under the lid. You can learn more about the PIXMA MG6821 HERE.
We hope this helps!
