120 DPI Graphics ESC L n1 n2 data
Selects eight wire double density (120 dpi) graphics for n1 + (n2 x 256) columns data.
Example: The following escape sequence will print six bytes of graphics data at 120 dpi. The resulting figure
will resemble a backslash character, “\”.
Escape Sequence: ESC L 6 0 128 64 32 16 8 4
Hexadecimal: 1B 4C 06 00 80 40 20 10 08 04
High Speed 120 DPI Graphics ESC Y n1 n2 data
Selects eight wire high speed double density (120 dpi) graphics for n1 + (n2 x 256) columns of data.
Horizontally adjacent dots may not be printed.
Example: The following escape sequence will print six bytes of graphics data at 120 dpi. The resulting figure
will resemble a backslash character, “\”.
Escape Sequence: ESC Y 6 0 128 64 32 16 8 4
Hexadecimal: 1B 59 06 00 80 40 20 10 08 04
High Speed 240 DPI Graphics ESC Z n1 n2 data
Selects eight wire quadruple density (240 dpi) graphics for n1 + (n2 x 256) columns of data. Horizontally
adjacent dots may not be printed.
Example: The following escape sequence will print six bytes of graphics data at 240 dpi. The resulting figure
will resemble a backslash character, “\”.
Escape Sequence: ESC Z 6 0 128 64 32 16 8 4

Printer Controls
Bell BEL
Causes the printer's bell to sound.
Control code: BEL
Hexadecimal: 07
Unidirectional Mode ESC U n
Selects unidirectional mode for n=1, or bidirectional mode for n=0. Printing is normally bidirectional.
Unidirectional printing provides more accurate positioning, but causes lower throughput.
Example: The following escape sequence will force unidirectional printing.
