Adding Control-D characters to PC files
The ADDCTRLD.BAT and CTRLD.PS files are located in the PHSR540 
directory on the Tektronix Windows 3.1 Driver and Printer Utilities diskette.  
These files are included for users who want to write their own 
PostScript files. 
Note
If your computer is connected to the printer through the parallel 
port, or the optional serial port, you need to use Control-D 
characters in your utility files or in the files you create.  However, 
if your computer is connected to a network such as NetWare or 
TCP/IP, you should not add Control-D characters to a utility file.  
The non-text Control-D character is required at the end of PostScript files 
sent to the printer’s parallel port, or the optional serial port; it signals 
“end-of-job.”  A Control-D should precede and follow most PostScript data 
files.  ADDCTRLD.BAT and CTRLD.PS help you add two Control-D 
characters to your files.    
ADDCTRLD.BAT
ADDCTRLD.BAT is a batch file that adds a Control-D to the beginning and 
the end of a file.  Use this file if you are creating your own PostScript files.   
To use ADDCTRLD.BAT, copy ADDCTRL.BAT and CTRLD.PS to the same 
directory on your hard disk.  Type the following command:
ADDCTRLD 
filename
where filename is the name of the file that needs Control-D characters.  
CTRLD.PS
CTRLD.PS contains some PostScript comments plus the Control-D character.  
Copy CTRLD.PS to the beginning and/or end of your PostScript files before 
you send them to the printer.  (PostScript utility files on the Tektronix 
Windows 3.1 Driver and Printer Utilities diskette already have Control-D 
characters at the beginning and end.)  You can send CTRLD.PS to the printer 
by itself to make sure the printer is in the “end of job” state.
