For a laser printer it is only the large black areas that have opacity problems and need over printing.
Don't double print thin traces.
Shrink ground/power planes by a little bit more than your average misalignment.
Only print the ground/power planes on the 2nd/3rd run
Expect an occasional wildly different feed position to ruin a print.
Inkjets (for me at least) don't have an opacity problem.
