Wake-Up Characters
The microFlash automatically goes into sleep mode in the number of
seconds you specified using your microFlash Configuration Program (see
Chapter 3). 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 characters are
needed for IrDA. For ASK/Pluse 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.
Tip: 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.
