The problem with using a copy machine would be if you want your quilt to be larger than the paper that the copy machine will hold. Printing it in multiple sheets, taping them together, then using it to paper piece would not work well, IMHO. Instead, you could draw the 1/8 wedge out on paper and use that for paper piecing. Each angle in the center is 45 degrees (found on most rulers) and the inner pieces are all diamonds. You could make it without paper piecing by just cutting your center diamonds, framing with white, and them framing again with other colors. It would be a very pretty pattern for a whole quilt top.
