[Caution] •Under DTR/DSR control, the printer sends the printer ID 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.
•Under XON/OFF control, the printer sends the printer ID 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 command receiving and printer ID sending
depending on the condition of the receive buffer.
•If ASB (automatic status back) is enabled by GS a, the host must discriminate
between the printer ID due to this command and the status due to ASB.
