[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 ASB starts. Then transmit the
current ASB status. After that during ASB is active, the selected enabled
ASB status is transmitted whenever the status changes.
• When n = 0, ASB is disabled. During ASB is disabled, ASB status is not
transmitted.
• Multiple status items can be selected.
• During ASB is active, ASB status is transmitted whenever the status
changes even if ESC = is not selected.
• This command setting is effective until the printer is reset or power is
turned off.

temporarily. Therefore you can not get the printer status change through
ASB status during block data [header – NUL] is transmitted.

• If the error status is enabled, a change in the following conditions will
trigger the ASB:
