    We've been using a LaserJet 4 with Transparencies for Laser Printers
    to make our negatives for over 10 years with very good results for
    making photopolymer patterns and dies. 

    Here are three things you may want to try. Most 600 dpi laser
    printers have enough toner density. If not, you can put two identical
    negatives in register with each other to increase the density. The
    more expensive option is a product called Laser Buddy that is an
    acetone based spray that increases the density of negatives made on a
    1200 dpi laser printer. Since it's acetone based it MUST be used in a
    well ventilated area.
