Chapter 4: Programming Commands 71 Revision C 12/09
A798-PG00001C
Transmit status
ASCII GS r n
Hexadecimal 1D 72 n
Decimal 29 114 n
Value of n: 1, 49 = printer status
2, 50 = cash drawer status
4, 52 = Flash memory user sector status
Transmits the status specified by n. This is a batch mode command which transmits the response after all prior data in the
receive buffer has been processed. There may be a time lag between the printer receiving this command and transmitting
the response, depending on the receive buffer status.
When DTR/DSR RS-232C communications handshaking control is selected, the printer transmits the one byte response
only when the host signal DSR indicates it is ready to receive data.
When XON/XOFF RS232C communications handshaking control is selected, the printer transmits the one byte response
regardless of the host signal DSR.
The status bytes to be transmitted are described in the three tables on the next page.
Exceptions
Unlike the A793, that had a dedicated connector and resultant dedicated status reporting for each cash drawer, the A798
has a single connector that shares data reporting from either cash drawer. When either cash drawer is open, an open status
is reported by the printer.
