You might think good thoughts about printing your Positive in mirror image so you can put the toner side against the copper, so the .010 or .020 thickness of the plastic overlay does not diffuse light onto your traces.
Im pretty sure thats how ive been doing it but ive been using an inkjet printer (with special inkjet PCB transparencies). Ive borrowed a laserjet now though and ive got some laserjet transparencies somewhere.
