Revision F January 2010
Busy line and fault conditions
If the printer is in error condition (cover is open, paper is
exhausted…), the printer will still accept data, respond to
the batch mode status commands (1B 76 and 1B 75 0),
handle the cash drawer commands, and not go busy until it
actually tries to execute a print command. Then it will stay
busy and stop processing data out of the receive buffer
until the condition clears. It will respond to the real time
commands as described below.
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
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.
Unlike the A756, that had a dedicated connector and
resultant dedicated status reporting for each cash drawer,
the A760 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.
