Backspace BS
Causes the current line to be printed, and then moves the current print position one space to the left.
The actual distance moved depends on the current character spacing. Backspacing can be done up to,
but not beyond, the left margin.
Control code: BS
Hexadecimal: 08
Vertical Position
Line Feed LF
Causes the current line to be printed, and then advances the paper one line at the current line spacing.
If “Auto CR” is set to “On” in the interface setup menu, a carriage return will also be performed.
Control code: LF
Hexadecimal: 0A
Variable Distance Line Feed ESC J n
Causes the current line to be printed, and then performs a single line feed of n/216ths of an inch.
0≥n≥255. Does not change the current line spacing. If “Auto CR” is set to “On” in the interface setup
menu, a carriage return will also be performed.
Example: The following escape sequence will advance the paper one half inch.
Escape Sequence: ESC J 108
Hexadecimal: 1B 4A 6C
Variable Distance Reverse Line Feed ESC j n
Performs a single reverse line feed of n/216ths of an inch. 0≥n≥255. Does not change the current line
spacing. If “Auto CR” is set to “On” in the interface setup menu, a carriage return will also be
performed.
Example: The following escape sequence will move the paper down one half inch.
Escape Sequence: ESC j 108
