Using Printer Control Codes
These control code definitions are organized by categories of
functions. Use the following methods to easily locate control codes.
Numeric order (single character codes only). Locate the index for
the control code, and turn directly to that page. For more
information, see
“Single Character Control Codes” on
page 132
. Locate the index for the control code, and turn directly
to that page.
Numeric order (complete list). Look up control codes by their
actual code values. For more information, see
“Escape Sequence
Quick Reference” on page 133
.
Backspace
Empties the print buffer. Moves the printhead 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.
