(2) SI (Shift In) (for condensed characters)
When the SI code is input, all data that follows it will be printed out in
condensed characters. This code is cancelled by the input of “DC 2” code.
The SI code can be input at any column position on a line, but all characters/
symbols on the line containing SI code are printed out in condensed characters.
Normal and condensed characters cannot be mixed on the same line.
When printing condensed characters, the data capacity of the print buffer will
become 132 columns per line (in terms of condensed size character). When
the SO code is received after the input of the SI code, condensed enlarged
characters (double width of condensed characters) can be printed. This
condition is cancelled by “DC 4” code or LF code, and the character size
returns to “condensed.”
(3) ESC SO
This code functions the same as the SO code.
(4) ESC SI
This code functions the same as the SI code.
(5) DC 4 (Device Control 4)
The DC 4 code cancels the SO mode (enlarged character printing function).
(6) DC 2 (Device Control 2)
The DC 2 code cancels the SI mode (condensed character printing function).
NOTE: The SO mode can be cancelled by the DC 4 code or LF code, but the SI mode can
be cancelled by the DC 2 code alone.
