The optional field can be any combination of the following letters:
T Total Field 4
O Overlay
S Sort by MICR line
U Unsuccessful report only
C Communicate - send report to host instead of printing
The report sent back to the host begins with SOH (0x01) and ends with EOT (04). Since
the reports can be quite long, they will likely be broken into separate buffers which may
be interspersed with non-audit buffers such as PJL JOB status. Each buffer will begin
with an STX character (0x02) and end with ETX (0x03).
Each record will be terminated with carriage return-line feed (0x0D 0A).
Start Audit Feedback Command

The printer will report to the host that sent this command every time an audit job
successfully prints.

56-95
96-111 SQ4
112-119
120-138

The printer will continue to report until it is cycled off and then back on.
