WHAT Am I Doing Wrong??

[PuNkEe1299]

I am trying to print mousekeeping envelope Disigns onto the smaller envelopes, and I cannot get it to print correctly. I have set my printer to the custom setting and put in the exact measurements, I have used the "envelope" choice where it asks me for my paper type. I just can't get it. I am using a Canon Pixma iP1700. Can anybody help me? Thank you!
