[Outline] This command selects which status should be the target of automatic status sending (ASB:
Automatic Status Back). Each bit has the following different meanings.
[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.
