Using Printer Control Codes
These control code definitions are organized by categories of functions.
The following methods assist in locating control codes easily:
• Alphabetically organized (complete list)—refer to the “Control
Codes and Escape Sequences” table on page 164. Locate the index
for the control code, and turn directly to that page.
• Numeric order (single character codes only)—refer to the “Single
Character Control Code Definitions” table on page 180. Locate the
index for the control code, and turn directly to that page.
• Numeric order (complete list)—refer to the “Escape Sequence Quick
Reference” table on page 183 and look up control codes by their
actual code values. Locate the index for the escape sequence, and
turn directly to that page.
Backspace
The print buffer is emptied. The printhead is moved to the left one
character space (using the current pitch). This can be performed to, but
not beyond, the left margin setting. The backspace is ignored if
justification of right, full, or centered is selected.
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.
Beeper
The printer produces a beep lasting approximately 1/10 of a second
