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. 5-73
