Real-time status transmission
GS sequence DLE sequence
ASCII GS EOT n DLE EOT n
Hexadecimal
1D 04 n 10 04 n
Decimal 29 4 n 16 4 n
Value of n:
GS/DLE sequence
1 = Transmit printer status
2 = Transmit RS-232C busy status
3 = Transmit error status
4 = Transmit receipt paper status
5 = Slip paper status
6 = Validation paper status
Transmits the selected one byte printer status specified by n command within a few msec according to the following
parameters. This command includes two sequences: GS (1D) and DLE (0
×
10).
Exceptions
The command is ignored if n is out of range.
An application using DLE (0
×
10) sequence must send EOT within 100 milliseconds of DLE or the printer will
misinterpret the DLE and execute a clear printer command. Avoid this possibility by using the ID 04 n sequence, which
is handled exactly the same as 10 04 n .
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.
