Hex 1B 76
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.
