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
Transmits the selected one byte printer status specified by
n in real time according to the following parameters. This
command includes two sequences: GS (1D) and DLE
(0x10).
Exceptions
The command is ignored if n is out of range.
An application using DLE (0x10) 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.
Unlike the A793, that had a dedicated connector and
resultant dedicated status reporting for each cash drawer,
the A795 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.
