For some printer features, you can use the downloadable utility files 
available on the Tektronix Windows 3.1 Driver and Printer Utilities diskette.  
To mount the diskette, refer to the instructions on page 4-6.  If you cannot 
use this diskette, refer to page 4-8 for instructions on obtaining the files from 
other sources.

You can use the utility files to perform a variety of tasks, such as changing 
the printer’s name, resetting the printer, and using an error handler. The 
utility files are written in the PostScript Level 2 programming language.  In a 
few cases, you may have to edit the utility files to change the default 
parameters.

A Control-D character is used to indicate the end of a file when printing 
through a parallel or a serial port.  Without a Control-D character in the file, 
the printer continues waiting for more input.  

All PostScript utility files, except RESET.PS, should start and end with a 
Control-D character when sent from a workstation over a parallel or serial 
interface.  In the file descriptions, Control-D is denoted as 

CTRL-D.  For 

more information about PostScript programming, refer to the PostScript 
Language Reference Manual, second edition, Adobe Systems Incorporated.
