True False Starts the printer toner saver mechanism Stops the printer toner saver mechanism Notes: • A PostScript job can override the effect of Screening by using sethalftone, setscreen, or setcolorscreen operators, unless Screening is set to IET or IETPictureGrade. • A PostScript job can enter or exit IET or PictureGrade using the Screening parameter in a setpagedevice call.
