The printer returns 8 bytes containing the boot and flash software version. The first 4 bytes returned are an ASCII string
for the boot version.
The second 4 bytes are an ASCII string for the flash version. Example: For 1.234.56 (8 bytes), the boot version is 1.23 and
the flash version is 4.56.

Real-time commands

The real time commands provide an application interface to the printer even when the printer is
not handling other commands:
• Real-time status transmission: GS (Hex 1D) sequence and DLE (Hex 10) sequence
• Real-time request to printer: GS (Hex 1D) sequence and DLE (Hex 10) sequence
• Real-time printer status transmission
The batch mode printer status commands are placed in the printer's data buffer as they are
received and handled by the firmware in the order in which they were received. If the paper exhausts while printing
data that was in the buffer ahead of the status command, the printer
goes busy at the RS-232C interface and suspends processing the data in the buffer until paper
is reloaded. This is true for all error conditions: knife home error, thermal printhead overheat, etc. In addition, there
is no way to restart the printer after a paper jam or to cancel a slip waiting condition when using the wait for slip
command.
The real-time commands are implemented in two ways in order to overcome the limitations of batch mode status
commands. Both implementations offer the same functionality; which one you choose depends on the current usage
of your application.
