CONTROL CODE DEFINITIONS
BEL Bell (07H): Receipt of a BEL code causes the beeper to sound for
approximately 1/2 second after any preceding printable data has
been processed.
BS Back Space (08H): Line terminator. The paper position remains
unchanged and the print position is moved left one character space
from the current. If the print position is at the left margin, no action
is taken.
CR Carriage Return (0DH): Line terminator. The print position is reset
to the left margin, and the paper position is left unchanged.
CSI Control Sequence Introducer (9BH): Signals the beginning of an
ANSI control sequence. When 8-bit data is used, CSI (9BH) can be
substituted for ESC [ (1BH 5BH). Also see ESC.
DC1 Device Control 1 (11H): Parallel and Serial Interface: Receipt of a
DC1 code with the printer in local mode puts the printer online
(selects printer) and enables receipt of data.
Through CCU menu options, a serial interface protocol may be
selected that transmits a DC1 code to the host to signal that the
printer is ready to receive data.
DC3 Device Control 3 (13H): Parallel and Serial Interface: Receipt of a
DC3 code when online places the printer in local mode (deselects
printer) and causes it to ignore all data except a <DC1>.
Through menu options, a serial interface protocol may be selected that
transmits a <DC3> code to the host to signal that the printer is not ready to
receive data.
ESC Escape (1BH): Signals the beginning of an escape sequence. See also
CSI above.
NOTE
The print position can also be set to the left margin via the
CCU Control Panel Menu using the SETUP/FORMAT/MODIFY
FORMAT/PRINT CONTROL menu selection.
(See note for <DC1), above.)
