I am using a canon bjc4000 printer with the bj800 driver using apsfilter. it works fine, but the printing goes realllllly slow. when i try to change the lights at the top to make it do less quality, it turns it back on when i try to print. does anyone know how to get this to print fast/lower-quality? lowering the DPI doesn't work---it prints at the same speed but very ugly.
