SAMPLE command | Comments about the output

  ESC [2J	 This escape string will clear the screen if ANSI.SYS is
		 installed. See the CONFIG.SYS DEVICE topic.

  ESC E > PRN	 This escape string will be sent to the printer. Notice 
		 the use of redirection (>) to accomplish this.

  BAT file that can be used if the ESC command is not present on your DOS:
@ECHO OFF
REM Usage: ESC character-string [device-name]
REM ^[ below should be an ASCII ESC character (27).
REM Redirection cannot be used to redirect the output of batch files, 
REM so a second (optional) device-name is allowed.
