Select paper with high opacity for duplex printing. Opacity refers to
how effectively paper blocks out what is written on the opposite side
of the page. If the paper has low opacity (high transparency), then the
printed data from one side of the page will show through to the other
side. For best results, print a small quantity to make sure the opacity
is acceptable.
