Trace over the printed embroidery design with a heat transfer pen or pencil. Press firmly; if the lines are too fine, the design will not transfer. Place the design on the fabric with the traced side down. To transfer the image, use an iron at a high temperature (without steam). If you are going to use it for digitizing embroidery you need to focus on the fabric quality first and the DST which are accepted by some of the embroidery machines.
