General Control Codes
Backspace
Description: Empties the print buffer. Moves the printhead left one character space (using the current
pitch). This can be performed to the left margin setting, but not beyond that setting. The
backspace is ignored if justification of right, full, or centered is selected.
Decimal: 8
Hex: 08
ASCII: BS
Notes: The backspace control code (BS) is not reliable when text contains different character
pitches. For reliable backspacing, use the escape sequence (ESC “\”), Set Relative Print
Position.
Cancel Line
Description: Discards all of the characters currently in the print buffer. Sets the current print position
to left margin. Text already printed cannot be cancelled.
Decimal: 24
Hex: 18
ASCII: CAN
Carriage Return
Description: Repositions the printhead at the start of the print line (usually at the left margin), and
repositions the pointer to the start of the print buffer, after printing all data in the buffer.
Also, all of the “one line” functions are reset, such as bold, double-strike, double-wide,
or unidirectional printing.
Decimal: 13
Hex: 0D
ASCII: CR
Notes: You can add an automatic line feed with a configuration item.
Delete
Description: Deletes the last character in the print buffer. This control code functions only in left
justification.
Decimal: 127
Hex: 7F
ASCII: DEL
