[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.
