If you can print your design with a laser printer it can be transfered with the aid of acetone, takes some practice to get the amount right on a cotton ball without washing the design away but it works, just be sure to reverse the patern before applying it as it will be mirrored.
I have also use a black sharpie to totally cover the object to be engraved and then lay the design over the piece and re-trace it out, works well for the main lines.
Jerry was using a transfer method where a inkjet printer was used with a transfer solution, the good part was the amazing detail of the transfer.
Hope This Helps Some.
