[Caution] [The specification which is common to the model]
• When the serial interface is used:
For DTR/DSR control:
The printer sends the status after verifying that the host is ready to receive. If the host is not ready to
receive, the printer waits for the host to become ready to receive.
For XON/XOFF control:
The printer sends the status without checking whether the host is ready to receive or busy.
• Because this command is executed when data is mapped in the receive buffer, there may be a delay
between receiving the command and sending the status depending on the condition of the receive buffer.
• If ASB (Automatic Status Back) is enabled by GS a, the host must discriminate between the status due to this
command and the status due to ASB.
• Whenever the Paper-end Sensor detects a "paper out" state, the printer goes offline, and the command is not
executed. Therefore, the printer never sends a status "No paper in Paper-end detector (0CH)".
[The specification which depend on the model]
