Wake-Up Characters
The printer automatically goes into sleep mode in the num-
ber of seconds you specified using your Configuration Pro-
gram. Thus, you must wake up the printer for it to receive
data and print. To do this, you may program a wake--up
character sequence into your hand--held device. Program
the wake--up character listed below at least six times for
baud rates of 9600 to the RS--232 port. You will need more
wake--up characters for faster speeds. No wake--up charac-
ters are needed for IrDA. For ASK/Pulse about 150 wake--
up characters are needed at 9600 baud.
The first character sent wakes up the printer; the next few
null characters will be lost during power--up.

NOTE: If you use the timer function, you may program wake--up characters
into your hand--held device. Refer to the manual that came with your
hand--held for programming information.

NOTE: Any character will wake up the printer. If a printable character is
used, you will see extra characters printed only if you use too many
to wake up the printer.
