The control sequence introducer (CSI) signals the beginning of an
ANSI control sequence that may accept parameters. In the 7-bit
environment, ESC [ is used. In the 8-bit environment, either ESC [or
the single code 9B may be used. 8-bit control is menu selectable.
When the printer recognizes that the escape sequence is invalid or is
not implemented, it will discard the characters received up to that
point. Subsequent printable codes will be printed.
In the 7-bit environment, an escape sequence is defined as a group of
two or more characters, beginning with the ASCII code 1B
(hexadecimal), which invokes a given printer function.
In the 8-bit environment, an escape sequence is defined as a single
character code which has its most significant bit set, or a group of
two or more characters beginning with the ASCII code 9B
(hexadecimal). When the parallel interface is used, the 8-bit
environment is always available. For the serial interface, single
character 8-bit controls are available if the interface has been set for
eight data bits via the printer menu. For either interface, single
character 8-bit controls must be enabled by menu selection.
Unless stated otherwise, any sequence received with illegal parameter(s)
will be ignored, however, their use is discouraged as this may cause
incompatibilities with future products.
