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
3, 51 = slip paper status
4, 52 = Flash memory user sector status
Range of n : 1–4
49–52
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 RS-232C communications handshaking control is selected, the printer transmits the one byte
response regardless of the host signal DSR.
When unsolicited status mode (USM) is enabled using the enable/disable unsolicited status mode command (1D 61),
the status transmitted by this command (transmit status) and the USM status must be differentiated according to
the information found in recognizing data from the printer. This is found in the real time commands section of this
document.
The status bytes to be transmitted are described in the following four tables.
Exceptions
When n is out of the specified range, the command is ignored.
The A776 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.
