Horizontal Position
Carriage Return CR
Causes the current line to be printed, and then sets the current print position to the left
margin. If "Auto LF: On" is selected in the "Setup: INTERFACE" menu, a line feed
will also be performed.
Control code: CR
Hexadecimal: 0D
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
Absolute Horizontal Tab ESC [ n `
Sets the current print position to column n. The actual position will depend on the
current character spacing. If n is less than the left margin, the active column will be
set to the left margin. If n is greater than the right margin, then a line feed will be
performed and the active column will be set to the left margin.
Example: The following escape sequence will set the active column to column 65.
Escape Sequence: ESC [ 6 5 `
Hexadecimal: 1B 5B 36 35 60
Relative Horizontal Tab ESC [ n a
Advances the current print position by n columns. The actual distance moved will
depend on the current character spacing. Equivalent to sending n spaces (SP).
Example: The following escape sequence will advance the active column by 10
columns. If current character spacing is 10 cpi, this will cause the print position to
move one inch to the right.
Escape Sequence: ESC [ 1 0 a
