[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.
