[Outline]	This command selects which status should be the target of automatic status sending (ASB:

		Bit			ASB Target Status		Hexadecimal	Decimal
		0	Drawer kick connector No. 3 pin status disabled				00	0
			Drawer kick connector No. 3 pin status enabled				01	1
		1	On-line/off-line status disabled				00	0

[Caution]	•	If none of the status is selected, the ASB function will be invalid.

•If any one of the status is selected, the ASB function will be valid, and the printer will automatically sends the 4-byte status every time the selected status changes.

•If ASB is valid when this command is handled, the current status will be sent unconditionally.

•See the tables on the following pages for the status to be sent.

•When sending the status, the printer sends 4 bytes without confirming the DSR signal status. The 4-byte status to be sent must be always successive except the XOFF code.

•Since this command is executed at deployment of the reception buffer, there may be a delay between command reception and status sending, depending on the reception buffer condition.

•If Printer Disabled is selected by ESC = (Selects Peripheral Device), this command will be invalid, but ASB will be always valid.

•When using DLE EOT, ESC u, ESC v, or GS I, it is necessary to distinguish the status of this command and ASB from that by the respective commands. See “6. Interface” for how to distinguish them.
