Automatic Ticket Voiding

This feature is enabled by adding a couple of esc sequences
to the beginning and ending of your session data. Once en-

job, the printer considers the print job incomplete and will
automatically print a VOID marker on the output in prog-
ress.
To enable ticket voiding you must send an ESC followed by
bt1 (0x1b, 0x62, 0x74, x031) to mark the beginning of the
print job, and ESC followed by bt0 (0x1b, 0x62, 0x74, x030)
to mark the end. If the printer sees a Bluetooth disconnect
