[Notes] ASB is the function that transmit the status of [cover open/close], [Online/
Offline] from the printer automatically. It is called [ASB function] and the
status is [ASB status]. If you use ASB, application can acquire the printer
change in a real-time and passively.
Select any status enabled (except n = 0) and basic ASB starts. Then
transmit the current basic ASB status. After that, while ASB is active the
selected enabled basic ASB status is transmitted whenever the status
changes.
When n = 0, basic ASB is disabled. When ASB is disabled, basic ASB
status is not transmitted.
Multiple status items can be selected.
When ASB is active, ASB status is transmitted whenever the status changes
even if ESC = is not selected.
This command setting is effective until ESC @ is executed, the printer is
reset or power is turned off.
During Block data [header - NUL] transmission, ASB is disabled temporarily.

Therefore you cannot get the printer status change through ASB status
when block data [header - NUL] is transmitted.
Any basic ASB status represents the enabled status whenever the status
changes. Therefore the disabled status items may change, because each
status transmission represents the current status.
The basic ASB statuses, corresponding to each bit for n are as follows:
