The printer has a power-off timer to conserve battery life. After a specified
period of inactivity occurs, the printer goes into sleep mode. This feature is
similar to the Auto-Off feature on your handheld.
The printer returns to normal mode when it starts receiving commands
again, but the countdown re-starts after every character received.
Before powering down, the printer transmits Auxon then Xoff.
