When you use this command, obey the following rules.
- After the host PC transmits the function data, the printer will send
response data or status data back to the PC. Do not transmit more data
from the PC until the response data or status data are received from the
printer.
- When operating with a serial interface, be sure to configure operation so
that the host computer uses the printer only when it is READY.
- With a parallel interface, a real-time status is stored in the transmission
buffer of the printer temporarily the same as the other transmission data
(except for ASB status), and when the host enters reverse mode, data is
transmitted in order from the beginning of the transmission buffer.
