[Notes]
• ASB(Automatic Status Back) transmits the status such as ink near-end, ink
cartridge installed/not installed automatically to the printer in real-time. It is
called [ASB function] and the status is [ASB status]. If you use ASB,
application can acquire the printer change in real-time and passively.
• Enabling any status (except n =0) starts ASB. Then the current ASB status
is transmitted. After that, when ASB is active, the selected enabled ASB
status is transmitted each time the status changes.
• When n = 0, ASB is disabled. During ASB is disabled, ASB status is not
transmitted.
• ASB status for ink is 4-byte, consisting of [header + status A + status B +
NUL].
• Header is [Hexadecimal = 35H/Decimal = 53]

• ASB is enabled if any status item is selected. The printer transmits a 4-
byte status when this command is executed. The printer automatically
transmits a 4-byte status message whenever the status changes. Each
status represents the current status.
