Samsung Bixolon SRP-500 Command Manual page 24

[Notes]
Even if only one of the statuses is enabled, the status is sent when this command is
executed. Subsequently, whenever the state of a valid status changes, that status is
sent. In this case, because the current state is shown for each status, there is a
possibility of a state change for a status for which ASB is not enabled.
If all statuses are disabled, the Automatic Status Back (ASB) function is disabled.
When transmitting a status, the printer transmits only four bytes.
Four bytes of status data must be consecutive, except for XOFF code.
This command is executed when the data in the receive buffer is developed. Therefore,
there may be a time lag between receiving this command and transmitting the status,
depending on the receive buffer status.
When the printer is disabled by ESC = (Select peripheral device), this command is
disabled but ASB is not disabled.
The status to be transmitted are as follows:
First byte (printer information)

0 Off
1 Off
2 Off
