ANSI X3.64 EMULATION
This section describes the control codes and escape sequences comprising ANSI
X3.64 emulation. This emulation may be selected by specifying "Mode: ANSI
X3.64" in the "Setup: INTERFACE" menu, or via software with the ESC ESC 1
sequence. While this emulation is selected, control codes and escape sequences from
other emulations are not available.
Control codes and escape sequences are used to control printer operation. An ASCII
control code is a single character in the range 00 hex through 1F hex, and 7F hex.
The ESC (Escape) control code (1B hex) is used to introduce character strings called
escape sequences, which provide an extension of the commands available with ASCII
control codes.
Many ANSI escape sequences begin with a two character Control Sequence
Introducer (CSI), Escape Left Square Bracket (ESC [, 1B 5B hex). If 8-bit data is
selected via control panel setup, these two characters may be replaced by a single
character CSI, 9B hex. The sequences are always documented in this section with the
two character CSI ( ESC [), because this format seems to be much more common, and
works equally well with 7-bit or 8-bit data.
Some escape sequences accept one or more numeric parameters.
parameter is a decimal number represented by a string of ASCII decimal digits ("0"
through "9").
Leading zeros may be supplied, but are not necessary.
implementation constraints, the largest value that can be accepted is decimal 255.
Larger values will be treated as zero. Omitting a numeric parameter is equivalent to
supplying a value of zero.
If a sequence accepts one numeric parameter, it will be represented as "n". If a
sequence accepts more than one numeric parameter, they will be represented as "n1;
n2; ... nx". Note that multiple numeric parameters are separated by a semicolon.
Most ANSI escape sequences will assume one of the following formats:
ESC f
ESC n f
ESC n1; n2; ... nx f
