Allows you to save toner or ink when making draft prints. It works by printing in light gray (darkness setting from 25% to 100%). It works with QuickDraw and PostScript printers - ink jet or laser printers, and it works with System 6 and System 7. The demo version works just like Tuner Tuner, but it prints obnoxious information in the center of each "Toner-Tuned" page.
