Xerox Phaser 300X 安装指南

Tektronix halftone screens are designed for Tektronix printers, and improve 
print quality over application-set halftone screens.  The Setscreen Off 
(SCRENOFF.PS) utility file redefines some PostScript operators, such as the 
setscreen, setcolorscreen and sethalftone.  When downloaded to the printer, this 
file prevents applications from overriding the Tektronix proprietary 
halftone screens.

Use the following utility files depending on your computer type:         

Install the utility files from the Phaser 300X printer’s CD-ROM; 
refer to page 2-2 for instructions.

Select the appropriate printer in the Chooser.  

Locate the LaserWriter Utility in the PhaserTools folder on your hard 
disk, and double-click its icon to start the application.  

Choose Download PostScript File from the Utilities menu.  

Select one of the Setscreen files from the list, then click Open.  
(These files were installed in the Printer Utilities folder inside the 
PhaserTools folder.) 

At the prompt  

Save PostScript output as:

 you are asked 

for a file name for saving printer output.  Use either the default 
name given in the edit box or type a new name.  

Click Save to send the file to the printer.

If no output is returned by the printer, the LaserWriter Utility 
displays a dialog box; click OK continue.
