[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.
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.
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]
