[Caution]			• If any status item is enabled, the status is sent to the host when this command is executed.
			After that time on, the status is sent each time an enabled status item changes. Because

each status item represents the current condition, status items disabled for ASB may also have changed.

•The ASB function is disabled if all status items are disabled.

•If the ASB function is enabled by default, the host receives the status the first time the printer gets ready for communication after it is turned on.

•The printer sends 4 bytes of status shown in the tables below, without checking whether the host is ready to receive or busy. The 4 bytes of status is a continuous string except for XOFF code.

•Because this command is executed when data is mapped in the receive buffer, there may be a delay between command receiving and status sending depending on the condition of the receive buffer.

•Even if the printer is excluded from the selection of peripheral equipment specified by the data input control command (ESC =), the 4 bytes of status is sent to the host whenever status changes.

•When DLE EOT, GS I, or GS r is used, the host must discriminate between the status due to that command and the status due to ASB.
