Heavy Paper--Which printer?

Hello,
I own a small buisness and decided to reward our employees who finish training a small diploma, or certificate.
I would like to make this "diploma like", so I plan on using thick paper, Parchment Paper.
I dont plan on mass printing anything, and at work will not be interested in Photo printing.
If its feasible a printed emblem with our company logo would be desired (if its not too hard)

So I would like someone to recommend me a suitable printer, Cannon or not.
Thank you in Advance.

You may come out cheaper designing it up and havig it printed at Kinko's or something? Unless you are wanting a new printer for more than just this task.

Hmmm...I would do something like that, but unfortunetly Im in East Africa, and we dont have Kinko's. I would love to print these myself, because they will come sparatically throughout the year.
