Phaser 240 Drivers and Utilities
Colors are printing incorrectly
Tektronix halftone screens are designed for Tektronix printers, and improve
print quality over application-set halftone screens. The Setscreen Patch utility
file redefines the setscreen, setcolorscreen and sethalftone PostScript operators.
When downloaded to the printer, this file prevents applications from
overriding the Tektronix proprietary halftone screens.
Use the utility files for your computer type.
