| Decimal | 27 | 118 |
[Description] | Transmits the current paper sensor status. | ||
∙When DTR/DSR control is selected, the printer transmits only 1 byte after confirming that the host is ready to receive data (DSR signal is SPACE).
∙If the host computer is not ready to receive data (DSR signal is MARK),
the printer waits until the host is ready. When XON/XOFF control is selected , the printer transmits only 1 byte without checking the DSR signal.
∙This command is executed when the data is processed in the receive buffer. Therefore, there may be a time lag between receiving the command and transmitting the status, depending on the receive buffer status.
∙The status to be transmitted is shown in the table below.
∙This command is available only with a serial interface, and is ignored with
a parallel interface.
