Chapter 4: Programming Commands 87
Revision D 12/09
A799-PG00001D
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 A799
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.
Printer status (n = 1 or n = 49)
Bit O/On Hex Decimal Status for transmit status
0 O 00 0 Paper present.
On 01 1 Paper exhausted.
1 O 00 0 Cover closed.
On 02 2 Cover open.
2 O 00 0 Paper present.
On 04 4 Paper exhausted.
3 – – – Undened.
4 O 00 0 Not used. Fixed to o.
5 – – – Undened.
6 – – – Undened.
7 O 00 0 Not used. Fixed to o.
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 specied 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.
