Select superscript / subscript mode 
EscSn (27)(83)n   <1Bh><53h>n 
  This command allows you to print superscripts or subscripts.   
  Set n to 0 to print subsequent text using superscript characters. 
  Set n to 1 to print subsequent text using subscript characters. 
  When you specify the value for n you may use the character codes for '0' and '1' (48 and 49) instead of 0 and 
1. 
  Selecting either superscript or subscript mode cancels double-height printing mode. 
  You can cancel either superscript or subscript mode with the Esc T command.

Select / cancel double-height printing 
Escwn (27)(119)n  <1Bh><77h>n 
  This command turns double-height printing on or off.   
  If n is set to 1 subsequent text is printed using double-height characters.  The line space setting is doubled. 
  If n is set to 0 subsequent text is printed using normal sized characters.  The previous line spacing is restored. 
  When you specify a value for n you may also use the character codes for '0' and '1' (48 and 49) instead of 0 
and 1. 
  You cannot use superscript, subscript or condensed printing modes in conjunction with double-height 
printing.  If you try to select any of these three modes while in double-height printing the command will be 
ignored.

underlined with a continuous line.   
  Horizontal tabbed spaces are never underlined. 
  If n is set to 0 subsequent text is not underlined. 
  When you specify a value for n you may also use the character codes for '0' and '1' (48 and 49) instead of 0 
and 1.
