[Caution] [The specification which is common to the model]
• 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 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 specified by
these commands and the status due to ASB.

• Bit 2 of the first byte (printer information) of the status sent in 4 bytes is set to 00h
because drawer is not supported.
