Forgett lasers for this purpose, these days, get a Canon Pixma 4300. An
alternative some time ago was the Epson Stylus C62 (set to premium
glossy photo paper quality), but it's no longer available. This way
traces down to 0.15mm are realistic and reproduceable and since no heat
is involved, distortion is no issue or if still present, linear and you
can compensate for it with something like CorellDraw etc.
