   TITLE:        Utility to send multiple printer control codes; 
   DATE:         06/08/1989; 
   DESCRIPTION:  "Sends a series of printer control codes (entered on the 
                 command line). Initially set up for Epson type printers, 
                 the control codes can be easily modified by changing 2 
                 tables in the header file pcon.h. One table is for control  
                 code data, the other is for on-screen help"; 
   KEYWORDS:     escape sequences, printer control, pcon.; 
   SYSTEM:       MS-DOS;
