I chose 2 paper type (Canon - Matte Photo Paper Canon High Resolution Paper MP101et HR101N) because Canon refused to send me samples that I can do a test, it's a shame on their part and it disappoints me much. Otherwise I used this paper to make thank you cards (front and back) and it has a very good record with my Canon MG7150, however a pity that Canon does not set the paper on the 2 sides for duplex because the rendering is unless of course one of the two sides, and none of their reference does this. As against the "Canon High Resolution Paper HR101N" really is less suited to what I wanted to do.
